Valgrind support for old Mac OS X versions

[Paul Floyd via macports-users]

Hi

I'm in the process of updating Valgrind's macOS support. We're a long 
way behind. At the moment 10.13 is the latest that we support. I expect 
that 10.14 support will land soon (and if all goes smoothly, 10.15 soon 
after that). 11 might take a bit more work.

At the same time I'd like to clean up code for platforms that we no 
longer support.

I have an old macbook with 10.7 on it and that is too old (Valgrind now 
requires C11 support and the configure stage also uses xcrun options 
that XCode 4.6.3 on 10.7 does not support). I have access to a 10.13 VM.


Is there anyone on this list that has access to Macs running versions 
between 10.8 and 10.12 that could do a test to see if Valgrind at least 
builds on those platforms?


TIA

Paul
