If you are changing the component, would not a better choice be "driver" than
"c"? 

I agree the patch does not touch the preprocessor code, but from a user point
of view it is a preprocessor issue. The 4.2.2 manuals say in section 3.11 that
"The preprocessor's direct interface is undocumented and subject to change, so
whenever possible you should avoid using -Wp and let the driver handle the
options instead." A user could reasonably (but wrongly) assume that the driver
passes options like -I to the preprocessor.

If you are changing the component, then can you change the severity to
something more suitable than "enhancment" at the same time? Whilst I am all in
favour of emitting warnings about obsolete features, until there is a working
replacement for -I- it is a bug to complain that it is deprecated.
