44 specific case since no sane compiler should be defining either
45 __BIG_ENDIAN__ or __LITTLE_ENDIAN__ unless it really is generating

87 configure but ensure that we also define them if configure was not used for

140 __WXOSX_OR_COCOA__ is a common define to wxOSX (Carbon or Cocoa) and wxCocoa ports under OS X.
142 DO NOT use this define in base library code. Although wxMac has its own
143 private base library (and thus __WXOSX_OR_COCOA__,__WXMAC__ and related defines are
144 valid there), wxCocoa shares its library with other ports like wxGTK and wxX11.
146 To keep wx authors from screwing this up, only enable __WXOSX_OR_COCOA__ for wxCocoa when
147 not compiling the base library. We determine this by first checking if
148 wxUSE_BASE is not defined. If it is not defined, then we're not buildling
149 the base library, and possibly not building wx at all (but actually building
150 user code that's using wx). If it is defined then we must check to make sure
151 it is not true. If it is true, we're building base.
153 If you want it in the common darwin base library then use __DARWIN__. You
154 can use any Darwin-available libraries like CoreFoundation but please avoid
155 using OS X libraries like Carbon or CoreServices.

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

381 test for old versions of Borland C, normally need at least 5.82, Turbo
382 explorer, available for free at http://www.turboexplorer.com/downloads
387 Older versions of Borland C have some compiler bugs that need
388 workarounds. Mostly pertains to the free command line compiler 5.5.1.
390 #if defined(__BORLANDC__) && (__BORLANDC__ <= 0x551)
392 The Borland free compiler is unable to handle overloaded enum
393 comparisons under certain conditions e.g. when any class has a
394 conversion ctor for an integral type and there's an overload to
395 compare between an integral type and that class type.
397 # define wxCOMPILER_NO_OVERLOAD_ON_ENUM
400 This is needed to overcome bugs in 5.5.1 STL, linking errors will
401 result if it is not defined.
403 # define _RWSTD_COMPILE_INSTANTIATE
406 Preprocessor in older Borland compilers have major problems
407 concatenating with ##. Specifically, if the string operands being
408 concatenated have special meaning (e.g. L"str", 123i64 etc)
409 then ## will not concatenate the operands correctly.
411 As a workaround, define wxPREPEND* and wxAPPEND* without using
