[Fontconfig] configure fails on expat.h

[Dege, Robert C.]

./configure errors out when trying to find the expat.h library.  I have expat-1.95.8 installed on my system in
the /opt directory.  I can see the expat.h file that it's looking for, but no matter what parameters I pass
to configure, it still fails to find the file.  Can someone tell me what I'm doing wrong??

# ./configure --prefix=/opt --with-expat-includes=/opt/include --with-expat-lib=/opt/lib
