I'm sure this has been reported.

General narrowing of a value (i,e double to int) needs to be reported, but
bit-fields narrowing should not be reported unless asked for. There is nothing
in "C" or "C++" to cast a bit-field, which in theory, would remove the warning.
This is a serious problem and it makes gcc 4.3 not usable!

Test case:

Compile "gcc" with -Wconversion.

Bit-field warnings need to be disabled We need a 4.3.3 patch otherwise we punt
on 4.3 release.
