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

   9 Compilation for target architectures other than i386, x86_64 or PowerPC
  10 (e.g. ARM) caused multiple warnings like the following to appear:
  11
  12   doomdata.h:75:1: warning: ‘gcc_struct’ attribute directive ignored
  13    } PACKEDATTR mapsidedef_t;
  14    ^
  15
  16 This was due to 'gcc_struct' being undefined for these architectures.
  17 Since that attribute was actually introduced by commit 87db726b9a9ae61ca
  18 to address the fact that -mms-bitfields became the default for GCC on
  19 Windows, limit it to that case.
