howto know what xemacs was compiled with

[Jaime H . Barrera]

Hi,

I am using xemacs 21.1.14 and my background pixmap is not displaying 
properly.  I am wondering if xpm or jpg support was built into this 
version that I am using.  So are there some build logs I can try to 
find, a lisp function I can execute from within xemacs or a variable the 
value of which will tell me the relevant info?

Also, if anyone has some tips as to why my background pixmap may not be 
displaying, I'm all ears.
