The description of `CPATH', `C_INCLUDE_PATH', `CPLUS_INCLUDE_PATH'
and `OBJC_INCLUDE_PATH' from the gcc info manual says:
[...]
`CPATH' specifies a list of directories to be searched as if
specified with `-I', but after any paths given with `-I' options
on the command line. This environment variable is used regardless
of which language is being preprocessed.
The remaining environment variables apply only when preprocessing
the particular language indicated. Each specifies a list of
directories to be searched as if specified with `-isystem', but
after any paths given with `-isystem' options on the command line.
[...]
The cause of the warnings that you see is that by the time defs.h is
parsed (last in the search path) some system header file already defined
the symbols __cdecl, __stdcall and __fastcall. So what are you looking for
is not `CPLUS_INCLUDE_PATH' but `CPATH'. Obviously you also have to fix
your include file to behave properly when __cdecl, __stdcall and
__fastcall are already defined.
