g_warning/g_error/g_message

[Dan Winship <danw ximian com>]

If you're using a non-GNU, non-C9X compiler, g_warning, g_error, and
g_message get defined as static functions in every single file that
#includes glib.h. Bug? (They used to be "static inline" but that got
changed a while back because apparently it broke something.) Shouldn't
there just be prototypes in glib.h and definitions in gmessages.c?
