Yes, a couple of months ago I too thought we would lose no porting targets
by assuming C99 or better. But I had forgotten about IRIX 6.5, where the
only available compiler for the 'o32' ABI is cc (at least on the machine
I have access to), and this cc does not grok statements after declarations.

Anyway, this pre-C99 support is not a lot of trouble.

It's more time-consuming to fix the various GC crashes that I'm observing
on the various porting targets...
