I had the same thing. Looking at the config.log output, it seems that 
the configure test is braindead - GCC reports no input files, thus 
returning an error. Unfortunately, my skills with the autotools don't 
suffice to be able to provide a patch for this. I worked around it by 
setting ac_cv_header_extensions_xrender_h=yes in the configure 
invocation. (Doublecheck the variable name, I'm working from memory here.)
