From d9c517d9a4e168c1f7ed28ad0eb9365d69f5ceb2 Mon Sep 17 00:00:00 2001

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.
