Partly sync with cygwin (the patch) and Arch (the packaging)
It's a bit mysterious where the cygwin patch is coming from,
it's in the src package, but not the git repo. And it likely
comes from some github repo, but I can't find it.
In some cases this will introduce cycles which could likely be cleaned
up by only depending on some unix tools instead of the whole autotools.
Rebuilding doesn't make much sense at this point since it just adds a subset
of base-devel which is still installed by default.
* upgrade some broken packages
* correct some broken urls/checksums
* use secure urls where possible
* use stable url for ncurses
* some whitespace fixes
Remaining md5sums either didn't download or
didn't pass checksum tests.
Uses a patch from Cygwin and is at the same
version. We won't be providing tk though as
that requires the X Windows System - unless
someone reverts the change that removed GDI
as a rendering back-end for Cygwin's tk.
This was added in support of expect which
was in turn added in support of dejagnu so
that libffi's testsuite can be run.
