Когда пытаемся скомпилировать программу, то получаем баг:
cc -m32 test.c
In file included from /usr/include/features.h:352,
from /usr/include/sys/poll.h:23,
from /usr/include/poll.h:1,
from ABftw_c.c:42:
/usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h: No such file or directory

Лечится это так:
yum -y install glibc-devel
