I have always relied on locale(1) for this stuff.  Why do we need to
override the locale in this script?

Note that even if locale(1) is installed, there may be no @euro locale
provided, such as on my laptop:

    $ locale -a | fmt
    C POSIX en_AU en_AU.iso88591 en_AU.utf8

FWIW, I have a /usr/bin/locale on SunOS 5.8 (Last change: 20 Dec 1996).

indicates it was part of the 2003 POSIX.1 spec.
