trouble with Xfont lib

[Frederik Nosi]

Today I tried installing xserver following the instructionson the site. 
Everything went fine till when I began building the Xserver module. There ld 
complained about an undefined function in Xfont. Looking more on this I found 
that the problem is that the file decompress.c is missing in 
Xfont/fontfile/Makefile.am
Addinf it and rebuilding Xfont fixed this issue. I'm not attaching a patch as 
this is trivial to just add it there.

Thanks,
Frederik Nosi
