STDCALL first patch

In C, stdcall function names  are automatically mangled with @n suffix
for cygwin and mingw, by code
#define TARGET_MANGLE_DECL_ASSEMBLER_NAME
i386_pe_mangle_decl_assembler_name
Other targets use the default no-op TARGET_MANGLE_DECL_ASSEMBLER_NAME
hook.

I don't know where all this DEC$ ATTRIBUTES stuff is 'officially'
documented but my google came up with this:
http://h21007.www2.hp.com/portal/download/files/unprot/Fortran/docs/lrm/
lrm0586.htm

which would seem to be a reasonable starting point for GNU$ ATTRIBUTES
