And if you meant "how we made the decision": it's only done by  
default for Darwin, because there libc is the only supported system  
interface, for "netware libc" (libc is the recommended netware system  
interface, but we also have a non-libc dependent netware port) and  
for solaris (less porting work than implementing full syscall support).

You can enable it for most (all?) *nix'es by compiling the rtl with  
OPT="-dFPC_USE_LIBC"
