I use i386 not x86_64, so building with pcc on x86_64 has not been
tested by me. It looks like pcc does not support the method used to
get the right argument register values loaded on x86_64, but I'm not
sure what the best solution would be. It would probably work, in the
mean time, to remove the asm entirely from __syscallN inline functions
and instead have them simply call the extern __syscall().
