fix compile problems in intl-encap* under VS6
-------------------- ChangeLog entries follow: --------------------
lib-src/ChangeLog addition:
2010-01-30 Ben Wing <ben@xemacs.org>
* make-mswin-unicode.pl:
Make it possible to specify an overridden prototype in cases where
either Cygwin or Visual Studio has errors in their headers that
can be corrected by falling back to a less qualified type (typically
without const).
src/ChangeLog addition:
2010-01-30 Ben Wing <ben@xemacs.org>
* intl-auto-encap-win32.c:
* intl-auto-encap-win32.c (qxeExtractAssociatedIcon):
* intl-auto-encap-win32.c (qxeExtractIconEx):
* intl-auto-encap-win32.c (qxeCreateMDIWindow):
* intl-auto-encap-win32.c (qxeCreateWindowStation):
* intl-auto-encap-win32.c (qxeDdeCreateStringHandle):
* intl-auto-encap-win32.c (qxeAbortSystemShutdown):
* intl-auto-encap-win32.c (qxeRegConnectRegistry):
* intl-auto-encap-win32.c (qxeGetICMProfile):
* intl-auto-encap-win32.h:
Rebuild.
* intl-encap-win32.c:
* intl-encap-win32.c (qxeUpdateICMRegKey):
Delete manual definitions of functions with former errors in
Cygwin headers but no longer. Use "override" with some functions
where Cygwin or VS6 accidentally omits a const declaration or
includes an extra one. Use "no" on SendMessageTimeout, which
has an error in the VS6 prototype (you could manually fix this
with an ifdef to split the Cygwin vs. VS6 calls, if we ever
actually used this function).

| 37 -- A time line for Lucid Emacs/XEmacs is | |
| 38 | |
| 2517 | 39 Version 19.0 shipped with Energize 1.0, April 1992. |
| 40 Version 19.1 released June 4, 1992. | |
| 41 Version 19.2 released June 19, 1992. | |
| 42 Version 19.3 released September 9, 1992. | |
| 43 Version 19.4 released January 21, 1993. | |
| 44 Version 19.5 released February 5, 1993. This was a repackaging of 19.4 with a | |
| 45 few bug fixes and shipped with Energize 2.0. It was a trade-show giveaway | |
| 46 and never released to the net. | |
| 47 Version 19.6 released April 9, 1993. | |
| 48 Version 19.7 was a repackaging of 19.6 with a few bug fixes and | |
| 442 | 49 shipped with Energize 2.1. Never released to the net. |
| 2517 | 50 Version 19.8 released September 6, 1993. (Epoch merger, preliminary I18N |
| 51 support) | |
| 52 Version 19.9 released January 12, 1994. (Scrollbars, Athena.) | |
| 53 Version 19.10 released May 27, 1994. Known as "Lucid Emacs" when | |
| 54 shipped by Lucid, and as "XEmacs" when shipped by Sun; but Lucid | |
| 55 went out of business a few days later and it's unclear very many | |
| 56 copies of 19.10 were released by Lucid. (Last release by Jamie Zawinski.) | |
| 57 Version 19.11 (first XEmacs) released September 13, 1994. | |
| 58 Version 19.12 released June 23, 1995. | |
| 59 Version 19.13 released September 1, 1995. | |
| 60 Version 19.14 released June 23, 1996. | |
| 61 Version 20.0 released February 9, 1997. | |
| 62 Version 19.15 released March 28, 1997. | |
| 63 Version 20.1 (not released to the net) April 15, 1997. | |
| 64 Version 20.2 released May 16, 1997. | |
| 65 Version 19.16 released October 31, 1997; retiring of v19 series. | |
| 66 Version 20.3 (the first stable version of XEmacs 20.x) released November 30, | |
| 67 1997. | |
| 68 Version 20.4 released February 28, 1998. (Jamie claims this version is the | |
| 69 "first reasonably stable release with MULE support" and says that "XEmacs | |
| 70 'core' and 'packages' now packaged separately.") | |
| 71 Version 21.0-pre5 released July 18, 1998. (Jamie says "Numbering scheme goes | |
| 72 wonky due to switch to stable + unstable branches.") | |
| 73 Version 21.0.60 released December 10, 1998. (The version naming scheme was | |
| 74 changed at this point: [a] the second version number is odd for stable | |
| 75 versions, even for beta versions; [b] a third version number is added, | |
| 76 replacing the "beta xxx" ending for beta versions and allowing for | |
| 77 periodic maintenance releases for stable versions. Therefore, 21.0 was | |
| 78 never "officially" released; similarly for 21.2, etc.) | |
| 79 Version 21.0.61 released January 4, 1999. | |
| 80 Version 21.0.63 released February 3, 1999. | |
| 81 Version 21.0.64 released March 1, 1999. | |

| 83 Version 21.0.66 released March 12, 1999. | |
| 84 Version 21.0.67 released March 25, 1999. | |
| 85 Version 21.1.2 released May 14, 1999; on comp.emacs, May 28. (This is | |
| 788 | 86 the followup to 21.0.67. The second version number was bumped to indicate |
| 87 the beginning of the "stable" series.) | |
| 2517 | 88 Version 21.1.3 released June 26, 1999. |
| 89 Version 21.1.4 released July 8, 1999. | |
| 90 Version 21.1.6 released August 14, 1999. (There was no 21.1.5.) | |

| 222 GNU Emacs version 15 (15.34) was released sometime in 1984 or 1985 and | |
| 223 shared some code with a version of Emacs written by James Gosling (the | |
| 224 same James Gosling who later created the Java language). | |
| 225 GNU Emacs version 16 (first released version was 16.56) was released on | |
| 226 July 15, 1985. All Gosling code was removed due to potential copyright | |

| 3893 The line above is original. Unfortunately, when an error is tripped | |
| 3894 inside of the handler (e.g. during Fbacktrace()), and the handler for | |
| 3895 the handler is invoked, it correctly notices that something is amiss | |
| 3896 and it should just return -- but it returns EXCEPTION_CONTINUE_SEARCH, | |
| 3897 which causes the debugger to be invoked debugging the handler code in | |
| 3898 this function -- and WITH THE STACK UNWOUND so that you see main() | |
| 3899 calling mswindows_handle_hardware_exceptions(), calling Fbacktrace(), | |
| 3900 and a crash a couple of frames in -- AND NO SIGN OF THE ORIGINAL CRASH! | |
| 3901 | |
| 3902 There's some real weirdness going on in the stack handling -- unlike | |
| 3903 in Unix, where further crashes just keep adding to the stack, it seems | |
| 3904 that under the structured-exception-handling, the stack can actually | |
| 3905 bounce back and forth between the full stack at the location of the | |
| 3906 exception and the unwound stack at the place where the __try clause was | |
| 3907 established. I don't completely understand it. What I do know is that | |
| 3908 returning EXCEPTION_EXECUTE_HANDLER on nested crash has the effect of | |
| 3909 aborting execution of the handler and going back to the outer filter | |
| 3910 function, which returns EXCEPTION_CONTINUE_SEARCH and everything is | |
| 3911 hunky-dorey -- your debugger sees a crash at the right location with | |
| 3912 the right stack. | |
| 3913 | |
| 3914 I'm leaving in the trickier Unix-like code in the handler; someone who | |
| 3915 understands better than me how the stack works in these handlers could | |
| 3916 fix it up more. As it is, it works pretty well, so I'm not likely to | |
