My gut says this is a Plan 9 problem: something tickled a bug in 8c.
I hope someone here can diagnose the issue.
I needed to modify /sys/include/bio.h as well as
/sys/src/libbio/^(bgetc.c bputc.c) to get this far in the Go build; I
have nothing against adding Bgetle2(), Bgetle4(), Bputle2() and
Bputle4() to libbio, I do wish I had seen that coming.
We do seem to be losing ground to the Go developers, I have a feeling
that it is going to be hard to catch up.

PS: One irritant I would gladly get rid of is the sheer number of
warnings that are being produced:
cmd/cc

how to eliminate them.
