Maurizio,

bogofilter's ./configure script tests all the warning options before
adding them to the gcc call.

If your gcc is 3.4, it supports all these options, including
-Wmissing-format-attribute, -Wsequence-point and -Wsystem-headers (and
their no- variants) - my 3.4.3 does, I just tried.

Plus, if the gcc driver had barfed, ./configure hadn't added these
options.

It appears as though your driver (gcc) and the actual compiler (cc1) are
not of the same version. Check the paths or reinstall gcc-3.4 with a
supported and documented procedure, then retry, and make sure there's no
-B option lingering around (this enables newer driver with older
backends).

Hope that helps,
