re: 3.81 and cygwin (revisited)

[Sandy Currier]

Hi all,

Well, having hit the problem regarding gmake using sh.exe on windows
as well as some other issues several weeks ago, I took a different
tack and tried to merge the 3.81 sources with the 3.80 cygwin sources.

It was a tad interesting, but I have a version of 3.81 built under cygwin
that is hobbling along.  It seems to fail no more tests then the native
cygwin 3.80 fails out of the box (6 I believe).

However, it only reliable builds stuff with -j2 or no -j.  With -j higher
than 2, the (outer) make process eventually seems to step on itself and
hangs with a bunch of non-existant subprocesses, and has to be manually
killed.

2 questions:

1) Is anyone interested in this cygwin port?  I would be happy to give it
away.  Note that the cywin mods conflict with the 3.81 mods.
2) Can anyone help suggest how do debug this further?  I am not a windows
developer, but here is the tail end of the output right before make hangs
with -j4:

thanks!
