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

682 __WXOSX_OR_COCOA__ is a common define to wxOSX (Carbon or Cocoa) and wxCocoa ports under OS X.
684 DO NOT use this define in base library code. Although wxMac has its own
685 private base library (and thus __WXOSX_OR_COCOA__,__WXMAC__ and related defines are
686 valid there), wxCocoa shares its library with other ports like wxGTK and wxX11.
688 To keep wx authors from screwing this up, only enable __WXOSX_OR_COCOA__ for wxCocoa when
689 not compiling the base library. We determine this by first checking if
690 wxUSE_BASE is not defined. If it is not defined, then we're not buildling
691 the base library, and possibly not building wx at all (but actually building
692 user code that's using wx). If it is defined then we must check to make sure
693 it is not true. If it is true, we're building base.
695 If you want it in the common darwin base library then use __DARWIN__. You
696 can use any Darwin-available libraries like CoreFoundation but please avoid
697 using OS X libraries like Carbon or CoreServices.
700 #if defined(__WXOSX__) || (defined(__WXCOCOA__) && (!defined(wxUSE_BASE) || !wxUSE_BASE))
701 # define __WXOSX_OR_COCOA__ 1
705 check the consistency of the settings in setup.h: note that this must be
706 done after setting wxUSE_UNICODE correctly as it is used in wx/chkconf.h
707 and after defining the compiler macros which are used in it too
709 #include "wx/chkconf.h"
713 some compilers don't support iostream.h any longer, while some of theme
714 are not updated with <iostream> yet, so override the users setting here
