New submission from Marc Culler <>:

Compiling an external module in the 3.7.0b1 prerelease on macOS High Sierra 
failed for me because a compiler named "gcc++" was not found.  As far as I can 
tell there is no such compiler in the current XCode release.  I don't know if 
there ever was one.  The culprit file is:


The following patch fixed the problem for me:

<  'CXX': 'gcc++',
>  'CXX': 'g++',
<  'LDCXXSHARED': 'gcc++ -bundle -undefined dynamic_lookup',
>  'LDCXXSHARED': 'g++ -bundle -undefined dynamic_lookup',
