rootcint: gcc wont exec cpp

For some reason, the existent and user+group+world-executable cpp
program on my Linux box will not be run by rootcint. Also, rootcint -?
doesnt explain what -p or +P does. Therefore, where are these options
explained?

===== using -p

When using +P, it appears that instead of specifying the directory in which the
include files exist, I must specify the directory and the include file
itself. Ie,

rootcint MyDict.C -c +P -I/usr/include/g++/builtin.h -I/felix/brannon/rs/VisionMagick/terry/String.Defs.h String.Vec.h LinkDef.h

This doesn't appear to be the case with -p.

However, the class still is not accepted:

brannon@palm ~/rs/VisionMagick/terry : rm MyDict.?
brannon@palm ~/rs/VisionMagick/terry : rootcint MyDict.C -c -p -I/usr/include/g++ -I/felix/brannon/rs/VisionMagick/terry paramVec.h LinkDef.h

=== using +P

The suggested command line also fails:

brannon@palm ~/rs/VisionMagick/terry : rm MyDict.?
