Greetings, and thanks so much for the feedback!
I watched the build, and it hung on a single step early on for 6h.
There is an instability forking children reliably. I've seen this come
and go on my machine.
Here is the relevant code, back from several years ago when cygwin was
32bit. The first branch should work unmodified, but posix_spawnp fails
with 'no error', hence the ifdef. I have likewise seen the
CreateProcess fail, but much less frequently.
At the point of failure, the program was trying to run 'ar x libfoo.a'
in a child and simply hung.
Suggestions?
Take care,
