GETTEXT_PACKAGE not defined

[Brook Keele <bkeele guidedfate com>]

I understand what gettext is, but glade is generating this bit of code.

#ifdef ENABLE_NLS
  bindtextdomain (GETTEXT_PACKAGE, PACKAGE_LOCALE_DIR);
  bind_textdomain_codeset (GETTEXT_PACKAGE, "UTF-8");
  textdomain (GETTEXT_PACKAGE);
#endif

The problem is: GETTEXT_PACKAGE isn't defined anywhere. On top of that I
can't find any good documentation that tells me what it is supposed to
contain. i.e. the location of gettext? 

Anyone else ever have this problem?
