Re: making more use of C99

[Paul Eggert]

This sounds reasonable, thanks.

One thing that bit me just yesterday is that with C99 you can't put a 
declaration immediately after a label. That's C23-ism, which GCC 
supports as an extension even in C90 mode (so I didn't discover the 
problem until I built with a non-GCCish compiler). That might be 
something you watch out for as you refactor declarations.
