64 first define Windows symbols if they're not defined on the command line: we
65 can autodetect everything we need if _WIN32 is defined

111 a lot of code (mistakenly) uses #ifdef _WIN32 to either test for
112 Windows or to test for !__WIN16__, so we must define _WIN32 for
113 Win64 as well to ensure that the existing code continues to work.

229 adjust the Unicode setting: wxUSE_UNICODE should be defined as 0 or 1
230 and is used by wxWidgets, _UNICODE and/or UNICODE may be defined or used by
231 the system headers so bring these settings in sync

276 OS: first of all, test for MS-DOS platform. We must do this before testing
277 for Unix, because DJGPP compiler defines __unix__ under MS-DOS

504 This macro can be used to check that the version of mingw32 compiler is

549 check the consistency of the settings in setup.h: note that this must be
550 done after setting wxUSE_UNICODE correctly as it is used in wx/chkconf.h
551 and after defining the compiler macros which are used in it too
553 #include "wx/chkconf.h"
557 some compilers don't support iostream.h any longer, while some of theme
558 are not updated with <iostream> yet, so override the users setting here

573 old C++ headers (like <iostream.h>) declare classes in the global namespace
574 while the new, standard ones (like <iostream>) do it in std:: namespace,
575 unless it's an old gcc version.
577 using this macro allows constuctions like "wxSTD iostream" to work in
580 #if !wxUSE_IOSTREAMH && (!defined(__GNUC__) || ( __GNUC__ > 2 ) || (__GNUC__ == 2 && __GNUC_MINOR__ >= 95))
