There's no risk of C being anything but the Good Olde Days:
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf
7.11 specifies C as a minimum environment.

POSIX strengthens this, check your setlocale(3posix) manpage (the
opengroup website is busy being broken, so no handy URL; but it's worth
installing the POSIX manpages if you don't have them yet):

       "POSIX"
              Specifies the minimal environment for C-language
              translation called the POSIX locale. If setlocale() is
              not invoked, the POSIX locale is the default at entry
              to main().

       "C"    Equivalent to "POSIX" .


LANG=C is more predictable then en or en_US.

Thanks
