Yes, I compiled 2.15 from the source on cygwin. Because I built it on
Cygwin it has a high likelihood of being correct. As for compatibility
with the GCC 3.4.3 that I used, it just seemed to work.

Well, we're into some new territory. When I figure out exactly what the
compatibility issues are, I probably will post a "you need version XYZ
of this and ABC of that". If those aren't regularly available, I'll
provide the binaries. But, I'm hoping to get this into "standard"
packages. I have no idea why Cygwin is the way it is, just that after
mucking around for a few days I found a combination that works (bin
utils 2.15 and GCC 3.4.3 both compiled on Cygwin).
