I don't know if it matters much.  Making it static could actually make the
overall stack smaller.  For windows, it's trivial to pull in the needed complib
source files statically, since it's one big build tree.  I initially tried to
limit the acm to only being dependent on libibverbs, but it's just too much work
long term to avoid using libibumad.  But I really don't want to have it depend
on opensm in order to pick up complib when a short header file can provide
what's needed.

er... yeah
