53 __WXOSX__ is a common define to wxMac (Carbon) and wxCocoa ports under OS X.
55 DO NOT use this define in base library code. Although wxMac has its own
56 private base library (and thus __WXOSX__,__WXMAC__ and related defines are
57 valid there), wxCocoa shares its library with other ports like wxGTK and wxX11.
59 To keep wx authors from screwing this up, only enable __WXOSX__ for wxCocoa when
60 not compiling the base library. We determine this by first checking if
61 wxUSE_BASE is not defined. If it is not defined, then we're not buildling
62 the base library, and possibly not building wx at all (but actually building
63 user code that's using wx). If it is defined then we must check to make sure
64 it is not true. If it is true, we're building base.
66 If you want it in the common darwin base library then use __DARWIN__. You
67 can use any Darwin-available libraries like CoreFoundation but please avoid
68 using OS X libraries like Carbon or CoreServices.

129 a lot of code (mistakenly) uses #ifdef _WIN32 to either test for
130 Windows or to test for !__WIN16__, so we must define _WIN32 for

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

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