Hmm.  There has meanwhile been another proposed patch to fix a similar

Could you try it out, please, without any other patches?

The DJGPP has no apparent effect on my igncr build; it fails to configure, so the testsuite cannot be run. Whatever is causing the DJGPP problem, it isn't exactly the same thing as the Cygwin bash igncr problem. I guess they are using some other method to throw away \r's.

Here are the testsuite results as of January 2009's 2.63.252-8aa9.

In (2) and (4), which patch would that be, the one you posted in

This is with the newer patch I just posted, which I think is closer to what Eric Blake had suggested.

For a failure, just post tests/testsuite.log.  For a hang, just run
something like
  make check TESTSUITEFLAGS='-v -d -x 27'

Thanks for the advice. Revisiting this issue, it looks like this hang is actually an intermittent hang. At least, it hung indefinitely twice the last time, and when I run individually, it doesn't hang (but it does fail). I'm going to try to run the testsuite again, and try a little harder to see if I can get a complete run out of it.

By the way, I've noticed on previous occasions that there are some parts of the autoconf testsuite that randomly fail intermittently on Cygwin every now and then. I don't know what this is about. I've noticed Cygwin fork() will sometimes fail for no obvious (to me) reason, so maybe this is it.
