Re: [BUGS] BUG #4186: set lc_messages does not work

Hi,

I posted a patch 18 days ago but have got no responce.
Anyway I've simplified the patch by using an appropriate gettext module.

AFAICS there are 2 causes.

1. MSVC version of postgres is using a bad gettext module.
2. getenv() in mingw cannot see the result of putenv() in MSVC8.0.

As for 1, we have to use another gettext module. I can provide it
if requested.
As for 2, pg_putenv() or pg_unsetenv() in the attachced patch calls 
corresponding putenv() whose result can be referenced by getenv() in mingw.

In addtion the patch provides a functionality to Windows locale
name to ISO formatted locale name.

Comments ?
