I guess that depends on the definition of "the correct locale".

The initial_setlocale sets the locale to the default locale or to what's
defined in the environment.  That's what a locale-aware application will
use as well, as soon as it calls setlocale(LC_ALL, "").  So what you get
in premain and dlls.init is the locale you'll use in the application.  A
non-locale aware application is usually supposed to use ASCII only and
all supported charsets are ASCII compatible anyway, so a non locale-aware
application shouldn't see much of a difference.

What problem are you trying to fix?

Indeed, thanks for catching.  I fixed that in CVS.
