I'm helping on the Sage maths project
http://www.sagemath.org/
where there are a large number of packages built, most of which ignore CFLAGS.
(Quite a few ignore CC and CXX too!) I'd like to display all the warnings, but
its hard when people overwrite CFLAGS.
Is there a way I can build gcc such that effectively "-Wall" is enabled all the
time?
If not, could anyone point me to where in the source code I might be able to
hack it, to build a version which displays all the warnings?
I think it would actually be quite a useful option to have when one configures gcc!
i.e
configure --prefix=/some/dir --always-display-all-warnings !!!
