225 test for old versions of Borland C, normally need at least 5.82, Turbo
226 explorer, available for free at http://www.turboexplorer.com/downloads
231 Older versions of Borland C have some compiler bugs that need
232 workarounds. Mostly pertains to the free command line compiler 5.5.1.
234 #if defined(__BORLANDC__) && (__BORLANDC__ <= 0x551)
236 The Borland free compiler is unable to handle overloaded enum
237 comparisons under certain conditions e.g. when any class has a
238 conversion ctor for an integral type and there's an overload to
239 compare between an integral type and that class type.
241 # define wxCOMPILER_NO_OVERLOAD_ON_ENUM
244 This is needed to overcome bugs in 5.5.1 STL, linking errors will
245 result if it is not defined.
247 # define _RWSTD_COMPILE_INSTANTIATE
250 Preprocessor in older Borland compilers have major problems
251 concatenating with ##. Specifically, if the string operands being
252 concatenated have special meaning (e.g. L"str", 123i64 etc)
253 then ## will not concatenate the operands correctly.

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

682 # define __WXOSX_OR_COCOA__ 1
686 check the consistency of the settings in setup.h: note that this must be
687 done after setting wxUSE_UNICODE correctly as it is used in wx/chkconf.h
688 and after defining the compiler macros which are used in it too
690 #include "wx/chkconf.h"
694 some compilers don't support iostream.h any longer, while some of theme
695 are not updated with <iostream> yet, so override the users setting here
