[m-dev.] for review: turn off -Wpointer-arith

[Fergus Henderson]

Estimated hours taken: 0.25
Branches: release main

scripts/mgnuc.in:
	Don't enable -Wpointer-arith, since for gcc < 3.0 it causes too many
	spurious warnings in system header files.  (This is fixed in gcc 3.0,
	though, so at some point we should re-enable it.)

 # -Wconversion		really only intended to help people using \`unprotoize'
 # -Waggregate-return	not useful, IMHO
