Subject: [PATCH] Fix "`gcc_struct' attribute directive ignored" warnings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Compilation for target architectures other than i386, x86_64 or PowerPC
(e.g. ARM) caused multiple warnings like the following to appear:

  doomdata.h:75:1: warning: ‘gcc_struct’ attribute directive ignored
   } PACKEDATTR mapsidedef_t;
   ^

This was due to 'gcc_struct' being undefined for these architectures.
Since that attribute was actually introduced by commit 87db726b9a9ae61ca
to address the fact that -mms-bitfields became the default for GCC on
Windows, limit it to that case.

Upstream-status: accepted, not yet released.
