problem with configure script and fdf support

We have a client that is using fdf with their current site (asp) and I was curious about the support in php. I found that the configure script had a problem, and was including -l by itself in the LIBS variable. The problem is on line 16436 (this is php 4.0.6, not sure if that matters) This line currently is written: if test $FDFLIBRARY = ""; then however, if there is no fdf library found, FDFLIBRARY is an empty string, so the line ends up: if test = ""; then and gives an error. I think a correct way to do this would be to write it: if test "$FDFLIBRARY = ""; then I'm not sure if this is the right place to put this, but I wanted to help
