Subject: Re: Turning off pointer signedness warnings (patch)
Date: Sat, 31 Dec 2005 12:40:10 -0500 [thread overview]
Message-ID: <E1EskiA-0006Pt-PV@fencepost.gnu.org> (raw)
In-Reply-To: <87fyoaclu5.fsf@stupidchicken.com> (message from Chong Yidong on Fri, 30 Dec 2005 16:32:34 -0500)
GCC 4.0 warns when a pointer to an unsigned object is passed to a
function that takes pointers to signed objects (or vice versa). In
older GCC's, this was a -pedantic warning; now, it's turned on by
default. (http://gcc.gnu.org/ml/gcc/2004-12/msg00841.html)
The GCC developers told me that this will be reversed in the next
release. Our complaints did win the day.
The following patch makes use of the new -Wno-pointer-sign option,
whenever it is available. If there are no objections, I'll check it
in soon.
Please do, and thanks.
