Flint build for 64bit on the way.
It seems there is an API bump from 15 to 16

These are new, so you can propose it

start reading from:
https://cygwin.com/packaging-contributors-guide.html

and we can follow up on cywin-apps mailing list

https://cygwin.com/mailman/listinfo/cygwin-apps

This is very appreciated. I can help you on that.

I never used Singular so my interest to update it was always
very limited;
last time it was mean Yue Ren to take care and I to just help him

https://sourceware.org/pipermail/cygwin-announce/2015-May/006150.html

but he never followed up on following releases.

About Singular last package build, the main issue in my opinion
is that the dynamic loading of "module" was transformed by Yue in a
static implementation.
I was trying to enable the dynamic loading but he preferred to
go for the current solution.
So I suspect the old patches could need an adjustment for the latest 
4.2.1p2 source code.

If you are really interested on taking over Singular maintainership
we can follow up by private mail.

Regards
Marco
