warnings...

["Gareth Pearce" <tilps hotmail com>]

Hi,
Previously it was mentioned that for things which applied to alot of 
packages here might be a better place to bring it up then bugzilla.
Now this is only a little thing, but given how many packages turn on -Werror 
on cvs by default, i guess that at least some of the developers dont like 
warnings much.
The deal is, new gcc's (3.2 at least) introduce a warning in cc1 when a 
system include directory is -I'd on the command line.  Most of the packages 
i have compiled recently, have had huge lists of these warnings, because 
$(prefix)/include is a system directory in my case, and it gets added alot.
Not sure what the optimal solution to this is, but a configure check could 
be done which get the list of system dirs from gcc - and then includes could 
be checked against that.
on the other hand - just checking to see if prefix/include is a system dir, 
would probably cover the most common cases.

Not that this bothers me much, since i compiled in a warning for implicit 
integer casts resuting in precision loss into my gcc - i now end up with far 
more warnings then anything else in the build logs.  (just have to remember 
--disable-more-warnings so i can get my build spam at all:P)

Regards,
Gareth
