Re: g++ defines for win32


Angel Tsankov wrote:

I downloaded g++ from cygwin and installed it. I noticed that it has built-in definitions of __stdcall, __cdecl and __fastcall. I've come across other g++ builds for Windows that do not have definitions for these identifiers, so I had to filter them out from my source code with the help of macros. Now I need to know how to distinguish this build of g++ from others in order to not filter the above identifiers out.
Here's what I have now:


#if !(defined (_MSC_VER) || (defined (__GNUC__) && defined (__WIN32__)))
#define __cdecl
#define __stdcall
#define __fastcall
#endif

gcc -dumpspecs:



*cpp:
%(cpp_cpu) %{posix:-D_POSIX_SOURCE} %{mno-win32:%{mno-cygwin: %emno-cygwin and mno-win32 are not compatible}} %{mno-cygwin:-D__MSVCRT__ -D__MINGW32__ %{!ansi:%{mthreads:-D_MT}}} %{!mno-cygwin:-D__CYGWIN32__ -D__CYGWIN__ %{!ansi:-Dunix} -D__unix__ -D__unix } %{mwin32|mno-cygwin:-DWIN32 -D_WIN32 -D__WIN32 -D__WIN32__ %{!ansi:-DWINNT}} %{!nostdinc:%{!mno-win32|mno-cygwin:-idirafter ../include/w32api%s -idirafter ../../include/w32api%s}}



For Cygwin (= -mno-win32 = default): __CYGWIN32__ __CYGWIN__ __unix __unix__ unix

For MinGW (= -mno-cygwin):
__MINGW32__
__MSVCRT__
WIN32
_WIN32
__WIN32
__WIN32__

For Cygwin (+ -mwin32):
__CYGWIN32__
__CYGWIN__
WIN32
_WIN32
__WIN32
__WIN32__
