I wonder how this worked the last time the package was built (in 2016!)

I guess since this variable is not exposed to the user, you could just 
rename it so it starts with a '_'.

But, it looks like there would be a general problem if anything in 
PKG_NAMES starts with a digit, as you wouldn't be able to assign to 
<PKG>_CONTENTS etc. in your cygport?

  I wonder if forbidding package names to start with a digit is the 
solution :)
