make the nls module compatible with windows 2000.
cannot use LOCALE_INVARIANT instead must lie and
say everyone is US English.  windows 2000 does not
have normalization functions and now doesn't have
case insensitive string comparison functions either
for languages other than English.

====================
This delta was composed from multiple commits as part of the CVS->Git migration.
The checkin message with each commit was inconsistent.
The following are the additional commit messages.
====================
LICENSE MIT

not all applications that link to cm_nls perform initialization.
Call initialization if it has not already been done explicitly.
