Problems using gettext on Windows

[Joerg Henrichs]

Hi,

I've been using gettext for a while in the game 'SuperTuxKart', and so 
far it has been working fine.

It was only when I tried to give the user the option to change the 
language from within the application, that I got problem on Windows: 
setting LANGUAGE inside of supertuxkart and then re-initialising (or 
even initialising for the first time) gettext does not work, I am still 
getting the original language (for the record, it works fine on Linux 
and Mac, and I can change the language before starting supertuxkart on 
Windows by setting LANGUAGE as expected).

I am using libiconv-1.9.1.bin.woe32.zip and 
gettext-runtime-0.13.1.bin.woe32.zip.

Reading your FAQ this is apparently a known issue, and I have tried to 
follow your recommendations there:

All components I compile from scratch are compiled and linked with /MD 
(multithreaded dll) - but supertuxkart depends on several other 
libraries (irrlicht, alut, ogg, vorbis, libcurl, ...) which are outside 
of my control. Not sure if they might interfere with anything.

To set LANGUAGE I tried using:
                bool r1=SetEnvironmentVariableA("LANGUAGE", "de");
                bool r2=SetEnvironmentVariableW(L"LANGUAGE", L"de");
                bool r3=SetEnvironmentVariable ("LANGUAGE", "de");
                int r4=putenv("LANGUAGE=de");
                int r5=_putenv("LANGUAGE=de");
(I tried everything I could think of ;) ) before initialising gettext.

But still the language in the game doesn't change.

I can confirm that apparently gettext is not calling the right getenv 
function (I set a breakpoint in getenv, and I can see that it gets 
called from supertuxkart and libcurl - but not from gettext). So I think 
your reason in the FAQ is still correct, but I don't know why a gettext 
should be using a different library to resolve getenv.

Any recommendations what I could do to fix this issue?

Thanks a lot for your time!

PS: Not sure if this is related: I have also problems using fprintf with 
gettext - it just crashes with
  Access violation writing location 0x00000010.
the first time a fprintf is done. I worked around this by adding a
#undef fprintf
after including libintl.h (which re-defines fprintf). Perhaps this might 
be somehow related to the above issue?
