These are the patches needed to get gcc8 working on CentOS 7.

The c99 requirement is the same as for gcc7.

For gcc8, --with-system-zlib was set unconditionally, which caused the
breakage for CentOS since it doesn't have zlib in base.  This probably
affects other platforms as well, but I took the conservative approach and
only fixed it for Linux.

Please respond if you have any concerns about these changes.


Hi Jason,

What does the failure look like? the package does depend on zlib, so I
wonder why it isn't picking up a pkgsrc-built zlib.

Here's the tail of the build output. I'm not seeing this with other gccversions of any other packages I'm aware of. Just gcc8.


Thanks,
