I see that this port is still broken in current. Here's a patch that gets
it to build properly on 3.0.

I believe it'll still build on 2.2.x with the above patch.
On 3.0, it works, and passes the setjmp_test and gctest, but fails on the
cordtest (coredump):
knife# gdb -q cord/cordtest

This may have something to do with how boehm-gc is given values for
DATAEND.
Oh, another thing. I checked this exact port (for boehm-gc 4.12) on 2.2.6,
and while it passed the setjmp_test and coredump test (the latter with a
few leakage warnings), it leaked all over the place with the gc_test.
I really really really would like this port to work, but I don't know or
understand how I can find out about stacks, data segments and memory
locations for them. Can someone recommend a good guide? Docs, preferably,
though I can probably figure this stuff out from sources (if someone points
me to the right areas). I've poked around src/lib/csu and, but am still
lost.
Thanks,
faried.
