The original reporter of this problem has since provided more=20
information.  Turns out the key mistake was that not only shouldn't our=20
configure be trying to test libgd features by running test links; it's=20
getting those testlinks critically wrong, too.  They don't use the=20
necessary libraries as reported by "gdlib-config --libs".  Moving this=20
fragment in configure.in:

   if test -n "$GDLIB_CONFIG"; then
     libgd_LIBS=3D`gdlib-config --libs`
   fi

to a point *before* we try AC_CHECK_LIB() calls on libgd features, might =

already help.  But the correct approach would be not to test links at=20
all, if gdlib-config is available: it already reports everything we want =

to know about libgd, including the feature selection.

So, to summarize: there is an error our configure.in that's causing=20
those problems, and there's no point in explicitly checking for -liconv=20
as a workaround.
