enhancement to cygport 34?

[Jason Pyeron]

Would this be an acceptable improvement?

I would like my cygport file to capture specific and deviant requirements. E.g. cannot compile with GCC 10+

The warning emitted is better than relying on a commit message or comment in the cygport.

                        fi
                        ;;
                esac



This would allow a BUILD_REQUIRES='gcc-core=9.3.0-2' or 'gcc-core=9\..*'

I choose = because it was never used in a version number for all the setup.ini I have cached on my system and it feels natural.
