Patch for ISO C function definition warnings from gengtype-lex.c

- Subject: Patch for ISO C function definition warnings from gengtype-lex.c
I haven't yet been able to get a new version of flex which fixes the
warnings in gcc so this patch implements option 4 from this
discussion: http://gcc.gnu.org/ml/gcc/2002-07/msg00138.html
It eliminates the "ISO C function definitions" warnings from
gengtype-lex.c.
Bootstraps on solaris2 still die late in stage2 for unrelated reasons,
but it got far enough that I can see the patch works. Assuming full
bootstrap succeeds when the unrelated bug is fixed, ok to install?
Thanks,
--Kaveh
