Pity if the dont:( I think I read somewhere that XFree could be compiled with optimisations and that the result was some 30% snappier code. I don't remember where I read it, but can this claim have some validity? BTW, when trying to compile XFree it simply does not work, as it cannot find Imake.tmpl. There is only a makefile in /usr/X11R6/src/xc. Haven't I got all the code?
