atomic_inc() inline function defined on kernel header file before redhat 7.2:
     usr/include/asm/atomic.h
On redhat 7.3, this function is not found in this file,
(perhaerps redhat  policy is changed.)
if you want to compile SCore and OpenMP on redhat 7.3 or newer,
you must install kernel source code on the host.
If you installed kernel-source rpm, atomic_inc() is defined following file:
    usr/src/linux-2.4/include/asm/atomic.h
And SCore 5.2.0 or later use the file.

So please install kernel-source rpm on the host, and recompile SCore and OMNI
again.
