I've improved the vlong support in 8c.
The missing ops are in, load/store optimizations,
and things like add, sub etc. aren't function calls.
A simple test (summing a large array of random
vlongs) shows a factor of 3 speed up on my
machine (braindead PII) so maybe I haven't been
just wasting time.
It's not ready for public consumption yet but I
have thrown a copy at presto and jmk.
I'll put it on my web-site in a few days.
Reading x86 assemb, let alone generating it is
starting to get to me.

ahh, i forgot that edf.c was vlong bound. you'll be
glad to know that i get a factor of 6 in a complex
expression - they tend to cluster around vlongs.
