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

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

201 Note that it must be included before defining hardware symbols below as they
202 could be already defined by configure

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

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

557 check the consistency of the settings in setup.h: note that this must be
558 done after setting wxUSE_UNICODE correctly as it is used in wx/chkconf.h
559 and after defining the compiler macros which are used in it too
561 #include "wx/chkconf.h"
565 some compilers don't support iostream.h any longer, while some of theme
566 are not updated with <iostream> yet, so override the users setting here
569 #if defined(_MSC_VER) && (_MSC_VER >= 1310)
570 # undef wxUSE_IOSTREAMH
571 # define wxUSE_IOSTREAMH 0

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