Normally, zic doesn't call setlocale, so it's running
in the C locale.  There is a compile-time option HAVE_GETTEXT
that enables setlocale but it's not set automatically.
The intent of HAVE_GETTEXT was to allow zic's diagnostics
to be internationalized; it was not to change the input
language of zic.  So perhaps the HAVE_GETTEXT stuff should
be removed; or if it's kept, the use of ctype.h primitives
should be removed (which'd be more work....).
