Building latest trunk with gcc 4.7: subversion/libsvn_fs_fs/index.c:351:1: warning: always_inline function might not be inlinable [-Wattributes] subversion/libsvn_fs_x/index.c:356:1: warning: always_inline function might not be inlinable [-Wattributes] subversion/libsvn_fs_x/index.c:339:1: warning: always_inline function might not be inlinable [-Wattributes] subversion/libsvn_ra_svn/marshal.c:398:1: warning: always_inline function might not be inlinable [-Wattributes]
If the inlining is really required, we should fix the code such that it either inlines the function or fails to compile, rather than this halfway mode. If inline is not required, we should demote the always_inline to a plain APR_INLINE, which should sidestep the warning.
