There are special makefile rules to handle this:

Not sure why it isn't working for gdb though.

Thanks. That was enough of a clue.

I was picking up an old version of gcc which did not support
-Wno-missing-field-initializers.  The makefile set
$NO_WMISSING_FIELD_INITIALIZERS to null.


  That looks like an issue to me, what version of GCC was that?  Perhaps we
should resort to -Wno-error for NO_WMISSING_FIELD_INITIALIZERS if the
actual option is not supported.

gcc-3.4.6. (RHEL 4)
