latest xulrunner (20.1) fails to compile on NetBSD 6.1_RC3 i386

[Dave Tyson <dtyson%anduin.org.uk@localhost>]

Just updated pkgsrc under 6.1_RC3 and attempted to build Firefox.
xulrunner is failing to compile:
It bombs out compiling nsMultiplexInputStream.cpp with a defined but not
used error. I had a quick look and the function is called from an
NS_ASSERTION.
