Seems like doing something > fancier than that is falling into the ``too smart by half'' category. There's a C compiler that optimizes tail calls? Where? There is no requirement in any standard that C prorams should be able to tail-call in constant space, and I'm not sure if it's even possible with all ABIs.. And definitely not possible with debugging, you need to have the stack frames in store. I wouldn't want to lose gdb backtraces 150 calls deep anyway. :) And this is of course just another point to prove that C can't be used well as a portable assembler.. :( Lauri Alanko la@iki.fi
