249 test for old versions of Borland C, normally need at least 5.82, Turbo
250 explorer, available for free at http://www.turboexplorer.com/downloads
255 Older versions of Borland C have some compiler bugs that need
256 workarounds. Mostly pertains to the free command line compiler 5.5.1.
258 #if defined(__BORLANDC__) && (__BORLANDC__ <= 0x551)
260 The Borland free compiler is unable to handle overloaded enum
261 comparisons under certain conditions e.g. when any class has a
262 conversion ctor for an integral type and there's an overload to
263 compare between an integral type and that class type.
265 # define wxCOMPILER_NO_OVERLOAD_ON_ENUM
268 This is needed to overcome bugs in 5.5.1 STL, linking errors will
269 result if it is not defined.
271 # define _RWSTD_COMPILE_INSTANTIATE
274 Preprocessor in older Borland compilers have major problems
275 concatenating with ##. Specifically, if the string operands being
276 concatenated have special meaning (e.g L"str", 123i64 etc)
277 then ## will not concatenate the operands correctly.

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

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