Re: gmake 3.81 and cygwin (revisited)

[sandy currier <sandy at releng dot com>]

Hi all,

Someone from the make-w32 at gnu dot org mailing list suggested I forward my
questions to this list.  Apologies if inappropriate.

Background:

A couple months ago, my project needed gmake 3.81 on windows.  After
looking at native gmake versus cygwin gmake, I decided to give merging
the 3.80 cygwin sources and the 3.81 fsf (CVS tip) sources a try.  For
the common base I selected the 3.80 fsf gmake release since that is
what the cygwin sources looked like they were based on.

Did the merge, and the result appears to fail no more tests then 3.80
appears to fail out of the box.  However, higher values of -j are
failing.

thanks!
