And here is the fix that I'll commit. Note that only S1_14 has
-fnative-struct, it was removed in CVS HEAD. However, gtk needs it or the
newer variant. To make matters simple, I introduce -mms-bitfields into
CFLAGS whenever gtk2 client is compiled on Windows only, and since I don't
add any checks for old versions of gcc (they are unlikely in this
context), compiling gtk2 on Windows using mingw32 now requires gcc 3.1 or
later. I'll comit this fix right away.
