Re: [Mingw-users] to_lower does not work with accents. valid locale names ?

[Tor L. <tm...@ik...>]

I think that the libstdc++ distributed by MinGW has been configured
with the "generic" C locale support only, which means that it supports
only the "C" locale. (Quite probably that is the only possible thing
to do for now for MinGW.)

Is there some way to see the configure switched passed when
configuring libstdc++, like gcc's -v ? Would it be a good idea if
MinGW offered also the build log files for download?

Check the configure.ac, acinclude.m4, and
libstdc++-v3/config/locale/generic/c_locale.cc in the gcc-4.4.0
sources.

If you can step down from the C++ ivory tower and use plain old C
library functions for your locale needs things might work better...
(and then indeed as you use the Microsoft C library, locale names are
of the form "Portuguese_Brazil").

If the functionality offered by the C library (or the part of its
functionality exposed by MinGW's headers, which miss declarations for
_mbslwr_l() for instance) is not enough, step even further down to the
Win32 API.

Or just use some middle level library like GLib that provides the
required functionality, also on Windows.
