Formerly, these options caused GCC to attempt to emulate a pre-
standard C compiler. They are now only supported with the -E
switch. The preprocessor continues to support a pre-standard mode.
See the GNU CPP manual for details.

I compiled gtk2.4.2 last weekend, but it was with a very old gcc, so I did
not see this problem. From my eyeball of glib-2.4.0/glib/gutils.h, I'd
guess the problem is the inline functions. It is difficult to know for
certain without seeing the warnings you are getting. I'd also say that
-Wtraditional is to help you keep your code clean of non-traditional
constructs. Since these are warnings, and not from your code, I suggest try
taking the -Wtraditional out of the compile. Of course you could try to
debug the cause of the non-traditional warning and submit a patch against
Glade if you have the time. :)
