[xemacs-hg @ 2002-03-13 08:51:24 by ben] The big ben-mule-21-5 check-in! Various files were added and deleted. See CHANGES-ben-mule. There are still some test suite failures. No crashes, though. Many of the failures have to do with problems in the test suite itself rather than in the actual code. I'll be addressing these in the next day or so -- none of the test suite failures are at all critical. Meanwhile I'll be trying to address the biggest issues -- i.e. build or run failures, which will almost certainly happen on various platforms. All comments should be sent to ben@xemacs.org -- use a Cc: if necessary when sending to mailing lists. There will be pre- and post- tags, something like pre-ben-mule-21-5-merge-in, and post-ben-mule-21-5-merge-in.

25 1. Keep in mind that there are two possible OS environments we are dealing 26 1. Keep in mind that there are two possible OS environments we are dealing
26 with -- Cygwin and Native Windows. Cygwin provides a POSIX emulation 27 with -- Cygwin and Native Windows. MS Windows natively provides
27 layer on top of MS Windows -- in particular, providing the file-system, 28 file-system, process, and window-system services through the Win32 API,
28 process, tty, and signal semantics that are part of a modern, standard 29 implemented by various DLL's. (The most important and KERNEL32, USER32,
29 Unix operating system. MS Windows also provides these services, but 30 and GDI32. KERNEL32 implements the basic file-system and process
30 through their own API, called Win32. When compiling in a Cygwin 31 services. USER32 implements the fundamental window-system services
31 environment, the Win32 API's are also available, and in fact are used 32 such as creating windows and handling messages. GDI32 implements
32 to do native GUI programming. 33 higher-level drawing capabilities -- fonts, colors, lines, etc.) The C
34 library is implemented on top of Win32 using either MSVCRT (dynamically
35 linked) or LIBC.LIB (statically linked). Cygwin provides a POSIX
36 emulation layer on top of MS Windows -- in particular, providing the
37 file-system, process, tty, and signal semantics that are part of a
38 modern, standard Unix operating system. Cygwin does this using its own
39 DLL, cygwin1.dll, which makes calls to the Win32 API services in
40 kernel32.dll. Cygwin also provides its own implementation of the C
41 library, called `newlib' (libcygwin.a; libc.a and libm.a are symlinked
42 to it), which is implemented on top of the Unix system calls provided
43 in cygwin1.dll. In addition, Cygwin provides static import libraries
44 that give you direct access to the Win32 API -- XEmacs uses this to
45 provide GUI support under Cygwin. The two environments also use
46 different compilers -- Native Windows uses Visual C++, and Cygwin uses
47 GCC. (MINGW, however, is a way of using GCC to target the Native
48 Windows environment. This works similarly to building with Cygwin, but
49 the resulting executable does not use the Cygwin DLL. Instead, MINGW
50 provides import libraries for the standard C library DLL's
51 (specifically CRTDLL -- #### how does this differ from MSVCRT and
52 LIBC.LIB?).)
