Thanks for the very detailed bug report! Before trying to go further,
could you please try this tarball, which includes an updated gnulib?

Thanks for the quick response Akim, will try that out ASAP!
The only information I forgot to include was that I copied your patch to
revert the autoconf upgrade from 2.68 to 2.71 as Cygwin currently only
has up to 2.69.
If it does not work any better, we'll probably have to dive into gnulib.
Spent part of yesterday there!
Will later be trying to rebuild fatal-signal.c in the released version
with -E to see what the expansions of gl_lock_lock, pthread_in_use, and
the value of glthread_in use look like.
Sorry to report still consistent failure mode, symptom, and location.
Please see attached.
Modified to run from below the non-standard SRC_DIR names, continue,
step to get failure, bt, then quit.
