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

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