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

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

774 RTTI: if it is disabled in build/msw/makefile.* then this symbol will
