Re: $CC and intel icc/ecc compiler

[Bob Friesenhahn]

It seems to me that both the before and after code is incorrect.  The
reason why I say is is that $CC may contain the command plus some
arguments which are required for it to behave in some consistent way.

This means that the if $CC is 'foo -bar' then

case $CC in
  foo)

will not match, but

case $CC in
  foo*)

will.  Parsing out just the first word from the specification would
solve the problem.

You should not expect that the user won't add compiler options to the
base compiler name since this may be required to select a compiler
version, target architecture, or some other global option which is
best specified via the compiler specification.
