The PC I am using today has a fairly recent but not completely current
Cygwin installation and it exhibits this problem when Norton AntiVirus
is enabled or disabled.

If I specify --build=i386-cygwin on the top level configure, I managed
to get configured but when it finished doing configure as part of make,
it failed with the build_alias message.

I can provide the "bash -x" log of a failed configure if anyone

Interestingly, I built a test m68k executable of "main() {}" and
tried to run it with NAV enabled and it was allowed with no
NAV messages.
