Subject: [PATCH 3/3] configure: Remove -Wredundant-decls on OS/2 to suppress
noise.
This warning causes too much noise in libc 0.6.6- headers due to
duplicate function decls here and there.

maybe iam missing someting but
gcc doesnt/shouldnt report warnings for "system headers" AFAIK

It's strange. If I build under /usr/local/src with the standard
environment (just tested with trunk), the warnings don't happen.
When I built 3.0.1 in its own directory with the environment set up to
find the libraries I'm linking against, eg $C_INCLUDE_PATH,
$LIBRARY_PATH etc defined, I get warnings such as
CC libavdevice/alldevices.o

Not totally sure if suppressing all redundant declarations is the best
option but it does quiet the noise.
I take it that Dmitriy is also building the RPMs in a separate environment.
