STEPS TO REPRODUCE: (Reduce the code in the README.ksh file as much as
possible)
/usr/bin/gcc -m64 -D__64BIT__=1 -O3 -mcpu=power8 -fabi-version=4 -std=gnu99
-I_END_XOPTS -DSPEC_CPU2000 -DSPEC_CPU2000_LP64 -DSPEC_CPU2000_LINUX_PPC32
-DSPEC_CPU2000_NEED_BOOL -DHAS_FGETPOS -DHAS_FSETPOS -fno-strict-aliasing -c
-o av.o av.c
