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.

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

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.
