Your question is not appropriate for this mailing list, which is about
development of GCC. For help using GCC please use the gcc-help mailing
list, thanks.

Please check if it's the same as an existing report in
http://gcc.gnu.org/bugzilla and open a new bug i not.

The "gnu" model is the only one that is complete. The
"ieee_1003.1-2001" model should work on Solaris, but does have some
issues.
If I ever find time I intend to work on the locale code to use the
POSIX 2008 xlocale features, which would provide the same
functionality as the "gnu" model but on more platforms than just
GNU/Linux.
