locale messages gnu patch 13631

[François Dumont <francois dot cppdevs at free dot fr>]

Hi

    First happy new year to all libstdc++ contributors and users !

    Here is my first patch of the year, for the gnu implementation of 
locale messages facet fixing normally DR 13631.

     More important is the test case coming next to it (4.cc) showing 
what it is fixing. The bad news is that I haven't been able to integrate 
this test to the libstdc++ testsuite so I join it to this mail but have 
no plan to add it to libstdc++ testsuite. It requires 2 different 
catalogs to play with and I haven't found how to tweak the makefiles to 
automatically generate those 2 catalogs as part of the testsuite. So I 
use the catalogs from okular (/usr/share/okular.mo) and pulseaudio 
(/usr/share/pulseaudio.mo), I hope those 2 are present on most of linux 
distroes so that someone can confirm that the patch is working.

    For info I even try to run this test with the gcc version coming 
with my distro 4.4.3 and it doesn't work neither so there is really a 
problem with my Mandriva 2010.2 distro.

    So, anyone can run the test for me ?

Thanks
