[tlbuild] asy on Macintosh

[Richard Koch]

John,

WARNING

At Mojca's urging, I downloaded gc 8.0.4. Then I directly used .configure and make to build the library on the Mac. No problems.

Then I added gc-8.0.4.tar.gz to the asy source in TeX Live and added a configure flag to use this version. The asy .configure log says it was used.

When compiling, I got exactly the same C++ errors as before. Mojca seems to compile either using macOS 10.6 or else using MacPorts. I do not believe this version of gc can be used with the current code when compiled on current Macs (and here "current" means Sierra and beyond, so for the last three years). Whether gc or asy is ultimately at fault I cannot say.

PS: To repeat last night's message, with the earlier gc and various other fixes, I compiled asy without errors and it seemed to pass all tests.
