[pulseaudio-discuss] Getting rid of annoying (but harmless) linking warnings

[Colin Guthrie]

Hi,

With the build looking so neat and tidy these days, I'm curious if I can
clean up one of the things that still bugs me a little!

It relates to the fact that I have a 64 bit system. My 64 bit libs are
in /usr/lib64, but the link path searches in /usr/lib and thus produces
the following:

libtool: link: gcc -std=gnu99 -I../../src -I../../src/modules
-I../src/modules -pthread -D_POSIX_PTHREAD_SEMANTICS

Note the -L/usr/lib just after libpulse.so in the above command.

I need to track down where this is introduced. Anyone with an
appropriately advanced autotools foo to help me work out where it comes
from so I can nuke it?
