Making gcc silent for third-party headers

[Paulo J. Matos]

Hi all,

I'm using gcc 4.1.1 and it is constantly spitting out (something along
the lines):
"class with virtual functions should have virtual destructor"
on third-party headers. I usually compile with -Wall, and I want to
keep that flag but disable it for these headers. Is there a way? Maybe
through #pragma?

Cheers,
