>Description:
The depcomp test for dependency tracking with the actula Intel
icc compiler (version 8.0) leads to depmode=gcc3, and a warning
about a unknown commandline option on each compile line (because of
the unknown option '-MP'.

In m4/depend.m4 there is aleady a special test for icc and unknown options,
but the stderr output seems to have changed since icc-7.1.

The attached patch enhances this test for the new icc-8.0 output string.

With the patch, the resulting depmode is depmode=gcc which works fine (for me).

Another solution would be running icc dependency tracking with
'-MD -MF' (without -MP), but I do not know how to achieve this ....
