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.

230 and is used by wxWidgets, _UNICODE and/or UNICODE may be defined or used by

557 Handle Darwin gcc universal compilation. Don't do this in an Apple-
558 specific case since no sane compiler should be defining either
559 __BIG_ENDIAN__ or __LITTLE_ENDIAN__ unless it really is generating
560 code that will be hosted on a machine with the appropriate endianness.
561 If a compiler defines neither, assume the user or configure set
562 WORDS_BIGENDIAN appropriately.

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

599 old C++ headers (like <iostream.h>) declare classes in the global namespace
600 while the new, standard ones (like <iostream>) do it in std:: namespace,
601 unless it's an old gcc version.
603 using this macro allows constuctions like "wxSTD iostream" to work in
