annotate src/s/cygwin32.h @ 5797:a1808d52a34a
If the position of a window's cached point is deleted, use buffer point instead
src/ChangeLog addition:
2014-06-17 Aidan Kehoe <kehoea@parhasard.net>
* extents.h:
* window.c:
* window.c (unshow_buffer):
* window.c (Fset_window_buffer):
Use extents, rather than markers, for the window buffer point
cache, so that when the text containing that window buffer point
is deleted, the window display code uses the buffer's actual point
instead of the position that the marker had been moved to.
Fixes Michael Heinrich's problem of
http://mid.gmane.org/6zr42uxtf5.fsf@elektra.science-computing.de ,
introduced by Ben's patch of
https://bitbucket.org/xemacs/xemacs/commits/047d37eb70d70f43803 .

| 20 /* Building under cygwin | |
| 21 * | |
| 442 | 22 * The approach I have taken with this port is to use primarily the |
| 23 * UNIX code base adding stuff that is MS-Windows specific. This works | |
| 24 * quite well, and is in keeping with my perception of the cygwin | |
| 25 * philosophy. Note that if you make changes to this file you do NOT | |
| 26 * want to define WIN32_NATIVE (formerly "WINDOWSNT"), I repeat - do | |
| 27 * not define this, it will break everything horribly. What does get | |
| 28 * defined is HAVE_MS_WINDOWS, but this is done by configure and only | |
| 29 * applies to the window system. | |
| 428 | 30 * |
| 31 * When building make sure your HOME path is unix style - i.e. without | |
| 32 * a drive letter. | |
| 33 * | |
| 34 * once you have done this, configure and make. | |
| 35 * | |
| 36 * windows '95 - I haven't tested this under '95, it will probably | |
