/sys$common/syshlp/helplib.hlb CC, Messages, BADLOCALE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Message        The compiler could not set its locale to either the
                locale-specific native environment or the "C" locale.

 Description    During start-up, the compiler was unable to set its
                locale.  As part of its initialization, the compiler
                will issue the call setlocale(LC_ALL, "").  If this
                call fails, the compiler will try to issue the call
                setlocale(LC_ALL, "C).  If this call also fails, the
                compiler will issue this message and abort.

 User Action    The best way to determine why the compiler is failing
                is to write a small program that contains the same
                library calls the compiler is making and then examine
                the return values.
