GNU "cpp -P" portability

[Thien-Thi Nguyen]

Is "cpp -P" POSIX?

I poked around at

 http://www.opengroup.org/onlinepubs/9699919799

and could find only matches to "preprocessor" rather than "cpp" in the
search facility, and so surmise "no", but thought i'd ask here anyway.
I suppose a portable workaround would be:

 cpp FILENAME | sed '/^#/d'

but have fingers crossed nonetheless...
