Undefined symbol _xstat in libX11

Configuring gtk+ 1.2.7 on i586-pc-linux-gnu fails when it begins
checking the X libraries.  Here is the tail of config.log:

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

I recently installed GNU glibc-2.1.2 and gcc 2.95.2.  Looks like I broke
something.  Any clues?

Thanx in advance,
