Backport #7746: Backport NSGetEnviron()/setproctitle.c fix for macosx
https://bugs.ruby-lang.org/issues/7746

Author: docwhat (Christian H旦ltje)
Status: Open
Priority: Normal

Target version: 


The fix for issue #6576 should be back ported to 1.9.3 as well.  Without it you cannot build shared ruby libraries that work reliably.  An example of this breakage is compiling something that uses the embedded library like vim; it crashes the instance vim tries to use ruby.

Here's the patch needed:
