Re: gthumb version 2325 compile -- GETTEXT_PACKAGE problem

I discovered that the autotools-generated config.h file contains no 
valid definitions at all, only lines of the form

/* Gettext package */
/* #undef GETTEXT_PACKAGE */

and similar. What could be the reason for this? I'm not experienced
with autotools, and I can't see any relevant errors in ./configure.log.
