Hi,
the following check in configure.ac fails with --as-needed but works
without it. Any hints what is wrong ? Thanks / Thomas

--------------------

if test $BUILD_ntl = no
then AC_LANG(C++)
     AC_CHECK_HEADER(NTL/version.h,,BUILD_ntl=yes)
     AC_MSG_CHECKING(for ntl library)
     FOUND=
     SAVELIBS=$LIBS
     for lib in "" "-lntl" "-lntl -lgf2x"
     do  test "$lib" && LIBS="$lib $LIBS"
	 AC_LINK_IFELSE( [
		 #include <NTL/tools.h>
		 int main () { _ntl_GetTime(); }
		 ],
	     FOUND=yes; break;,
	     LIBS=$SAVELIBS)
     done
     if test "$FOUND"
     then if test "$lib"
	 then AC_MSG_RESULT([$lib])
	 else AC_MSG_RESULT([none needed])
	 fi
     else AC_MSG_RESULT(none found)
	 BUILD_ntl=yes
     fi
fi

The fundamental theorem of algebra is open source. Like any other
mathematical theorem it can be applied free of charge and everybody
has access to its proof and can convince himself how it works. Why
should software be any different?
