That's not what the phrase from the info docs (GCC's info docs, not glibc's) is trying to say; it's trying to say it doesn't change to (say) the EABI ABI instead of the SysV one. That said, I -think- it'll work. Haven't tried it, though, and it does change the stack alignment logic in GCC somewhat. -- Daniel Jacobowitz MontaVista Software Debian GNU/Linux Developer
