The regular expression filters for determining the Intel compiler
version in the AmberTools configure script do not work correctly
(anymore?). Those are the relevant lines:
> icc_version=`$cc -v 2>&1`
> icc_version=`echo $icc_version | sed -e 's/\..*//g' | sed -e 's/^Version //'`
> ifort_version=`$fc -v 2>&1`
> ifort_version=`echo $ifort_version | sed -e 's/\..*//g' | sed -e 's/^Version //'`
On my system, $icc_version then contains "icc version 12" instead of
only a number, leading to the "integer expression expected" error. A
simpler approach would be:
$ icc -dumpversion | sed -e 's/\..*//g'
12
I am not sure if the -dumpversion switch works for older Intel compiler
versions.
Is it still correct that Intel compiler versions higher than 11 must be
treated specially, as stated in the AmberTools configure script? ->

With the "integer expression expected" error, this block is *not*
executed. However, the build result is obviously working properly. Can
this check be removed?
