+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.
