For the locale stuff, you're not exporting LC_ALL, which means if LC_ALL
is unset, and LC_MESSAGES is set, gcc might still spit out French (for
example) error messages. Also, it can be made simpler: changing the
command to `LC_ALL=C ${myprog} [EMAIL PROTECTED] -E - 2>&1` should do it. LC_ALL
overrides LANG, so that can be left alone, and adding it right in front
of the command makes sure it gets exported, but not in the current
shell, so there's no need to manually restore it.
