It looks like gcc 3.4.6 is throwing a warning when anonymous inner
functions (AKA "trampoline functions") are used, which is causing the
configuration script to stop. I need to add a flag to the configuration
test that will suppress this warning.
Unfortunately, I can't find a place to download Gentoo 3.4.6-r2, so I
can't install it and test this myself. In fact, I can't find any
information about that release at all. Can anyone help me out with a link?
