Subject: [PATCH] Merged revisions 115276 via svnmerge from
https://origsvn.digium.com/svn/asterisk/branches/1.4
........
r115276 | file | 2008-05-03 22:43:26 -0300 (Sat, 03 May 2008) | 2 lines
Treat warnings as errors when checking if a GCC attribute exists. We have to do this as GCC will just ignore the attribute and pop up a warning, it won't actually fail to compile.
