Here is a thread that I started a while back that discusses this issue:

http://lists.gnu.org/archive/html/help-make/2010-04/msg00052.html

I very much would like to see this issue resolved, but I agree with
Paul that the #pragma syntax may not be the best way to do it.

I think that some sort of new syntax (see the thread below that Paul
linked to) would be useful:
