This is not invalid according to:
http://gcc.gnu.org/onlinedocs/cpp/Implementation_002ddefined-behavior.html
Which says the following (unless that is not up to date also):

Treatment of a `#pragma' directive that after macro-expansion results in a
standard pragma.
No macro expansion occurs on any `#pragma' directive line, so the question does
not arise.

Note that GCC does not yet implement any of the standard pragmas.
