Seems to work for me:


gcc -Wmissing-prototypes foo.c -c
foo.c:1: warning: no previous prototype for `f'
[law@ralph /usr/tmp/egcs/gcc] gcc -v
Reading specs from /usr/egcs/lib/gcc-lib/i686-pc-linux-gnu/egcs-2.91.57/specs
gcc version egcs-2.91.57 19980901 (egcs-1.1 release)

I also get the error with the mainline sources.
