one more note about executable size in memory:
while there was no difference in sizes in memory for all gcc versions
for icc versions there was a great difference:
VERSION VIRT RSS
gcc (all) ~2000kb 500kb
icc10 (all) ~5500kb 800kb
but that should be obvious due to the additional linking in icc to libimf.so,
libintlc.so.5, libsvml.so, libgcc_s.so.1, libpthread.so.0 and libdl.so.2
that can possibly be countered to make a more fair memory usage comparison
between icc and gcc by modification to my icc.cfg configuration files, which
were when compiling this program:
http://manoa.flnet.org/icc10.cfg
http://manoa.flnet.org/icc11.cfg
