[patch windows i386]: Make sure that really-external functions aren't dllexported

[Kai Tietz]

Hi,

this patch takes care that for C/C++ inlines aren't dll-exported.

ChangeLog

2013-09-11  Kai Tietz  <kti...@redhat.com>

    * config/i386/winnt-cxx.c (i386_pe_type_dllexport_p): Don't
    dll-export inline-functions.
    * config/i386/winnt.c (i386_pe_determine_dllexport_p): Likewise.

Tested for x86_64-w64-mingw32 and i686-w64-mingw32.  I will apply this in
a couple of hours, if there are no objections.

Regards,
Kai
