Yes, but that won't work from libtool.  libtool isn't going to know what 
other dlls you happen to be building in your project.  (I don't actually 
know libtools internals yet, and never really wanted to. :)  So this 
might need to be some ugly add-on to the Makefile *sigh*.

OMG! It puts SQL Server on there now?  Thanks for the info, I forgot 
about all of this crap.

Ok, thanks. I have a license for Windows 7 and while I know that Windows 
10 is "free" I'm just not ready for that step.  I will probably have to 
eventually setup a win10 vm though.

Yeah, I usually prefer to build it myself.  I did test the git 
cygwin1.dll and it didn't fix the broken pipes (when running make check 
with more than one -j job).  As I've said before, I'm sure there's a 
race somewhere in Cygwin or some other Cygwin package(s). If I follow 
through with making this into a repeatable process, I'll likely have to 
try to diagnose it.
