Of course not, although I suspect most UNIX installations use it.  By "pre-GCC" 
I meant, what, late '80s or early '90s, before GCC came into widespread use?  
When commonly used optimizer technology wasn't nearly as good as it is now.  Do 
the non-GCC compilers (those that have halfway decent optimizers -- those that 
don't should only be used for bootstrapping GCC or other modern compilers) 
still need "register" these days to indicate what variables belong in 
registers, or do the optimizers do a reasonable job of working it out for 
themselves?
