/* 
   This is a simplified version of gettext written by Ulrich Drepper.
   It is used for the Win32 version of GnuPG becaise all the overhead
   of gettext is not needed and we have to do some special Win32
   stuff.  I decided that this is far easier than to tweak gettext for
   the special cases (I tried it but it is a lot of code). wk 15.09.99
