[ITA] Patch: update to source-highlight-3.1.9-1 (remove dep. to boost-1.66)

[Carlo B.]

Hello,
with reference to the recent release of the test version of Boost C++
1.90.0 libraries,

https://cygwin.com/pipermail/cygwin-announce/2026-January/012793.html

it may happen that you won't be able to remove previous version
because some packages depend on them. So, it happened to me that I was
not able to uninstall completely the older version 1.66 because
source-highlight package needs it.
I don't remember why I had to install it, however I took the chance to
update current version from 3.1.8 to 3.1.9, rather than simply
rebuilding.
You can find it here:

https://github.com/carlo-bramini/packages-cygwin/tree/main/source-highlight/source-highlight.x86_64

The rewritten script for cygport also adds missing information like
license and dependencies.
If you are planning to abandon the older versions of Boost C++ in
favour of the new one, this update may be used for removing this
dependency.

I hope that you will find it useful.

Sincerely,

Carlo Bramini.
