On most UNIX systems you need the 'native' compiler to build the  
kernel parts.
It _won't_ work otherwise. (There were people trying to use gcc on  
SGI IRIX and IBM AIX.)
This is something we know for a long time, and I don't see how  
that'll change.

So, if someone is to redo the compiler recognition make sure all the  
work is not completely useless.
You can't use servers (the userland processes) on HP-UX, IBM AIX, and  
SGI IRIX systems without having the kernel module loaded,
thus you won't gain anything by compiling the userland parts with  
gcc. You still need the 'native' compilers.

The only platform where those checks really matter is maybe Linux.

Don't get me wrong, there is room for improvement in the automated  
recognition magic there, but I don't think it's really worth the  
effort on all platforms.
