Wrap variables that were only used RE_ENABLE_I18N in `#ifdef
RE_ENABLE_I18N`. This eliminates compiler warnings when compiling with
NO_REGEX=YesPlease.

Hmm, this unfortunately is not enough for me to compile it locally.

The fix should be straightforward, and I think it should be squashed with
the header ANSIfication you sent earlier.

That's odd. The old regex library only used k&r style function
declerations *except* for regerror, and only then because a variable
name conflicted with a Windows typedef.

Could you compile the old compat/regex library on the same system?
What compiler/version/flags are these?
