Branches: main, 11.07 Avoid problems with the inclusion of windows.h in the runtime and a few standard library modules. By default, windows.h includes a lot of other header files, some of which conflict with other parts of the Windows API. Such a conflict occurs with G12 tcp module where the inclusion of winsock2.h conflicts with the inclusion of winsock.h by windows.h. We can avoid this by defining the macro WIN32_LEAN_AND_MEAN. It causes winsock.h and some other headers not to be included by windows.h. (Should the other headers actually be required -- the Mercury runtime and standard library do not require them -- then they will need to be included separately.) To make this (and other workarounds for silly things in windows.h) possible this change adds wrapper header for windows.h to the runtime. We now use this wrapper header throughout the rest of the system rather than including windows.h directly. runtime/mercury_windows.h: Add a wrapper around windows.h that allows us to control how windows.h is included in a consistent manner. Define WIN32_LEAN_AND_MEAN in order to avoid problems with code that uses winsock2.h. runtime/Mmakefile: Include the new header. runtime/mercury_memory.c: runtime/mercury_memory_handlers.h runtime/mercury_memory_zones.c: runtime/mercury_timing.c: library/dir.m: library/io.m: library/time.m: Include mercury_windows.h rather than directly including windows.h.
