	Try -Wall compilation. It warns badly (gcc-3.2.2) about the code has no 
effect and so on, which looks ugly to me. This patch has the same result 
(code has no effect), but without warnings from compiler.

	My bad. Sorry. It seems that prototype was changed. So this is really

	Again - gcc warns about 'code has no effect'...

	True. Unisth.h is needed for isatty().
