Once a blocker for GCC 8.1 appears I'll add this to that

I'm not sure of Bellagio is still developed or not

The solution others are adopting is to add the -Wno-error=array-bounds CFLAG, which makes it build on gcc82.  I have not investigated whether the warning represents a legitimate correctness problem in the code.  This project is apparently dead upstream.  So... caveat emptor.

Masking this package for removal. WONTFIX.
