ngettext on win32

I've been using the gettext extension with php 4.2.1 on win32. I have found that the plural gettext functions are not available (ngettext(), dngettext(), dcngettext()). The manual says these functions should be available above 4.2.0, and these functions do work in 4.2.1 on linux. Looking at the code in the CVS I see that these functions are wrapped with conditional directives: HAVE_NGETTEXT, HAVE_DNGETTEXT, and HAVE_DCNGETTEXT. These directives are set in /ext/gettext/config.m4 if the proper libraries exist. However these directives to do not appear at all in /ext/gettext/gettext.dsp (the win32 project file). Is this an oversight or is there a reason the plural gettext functions are not available in the win32 build of php? Thanks, nathan
