It doesn't look good:

robb at nepal:/raid/checkouts-raid/robb/nepal$ xlc_r -q64 -O0 -g
-qlanglvl=extc1x -o urandom urandom.c

robb at nepal:/raid/checkouts-raid/robb/nepal$ ./urandom

open O_RDONLY failed

open O_RDONLY | O_CLOEXEC failed

robb at nepal:/raid/checkouts-raid/robb/nepal$ uname -a

AIX nepal 1 7 00FA7FB84C00
