ghostscript 9.52 fails to build on macOS 10.13.6

The log looks similar to the one in ticket #61306

the FF_ structs may come from freetype, which I see was very recently updated.... might be a place to look.

[chrstphrchvz (Christopher Chavez)]

FF_stream_read(), FF_stream_close(), etc. are all functions defined (without prior declaration but before any subsequent usage) in the same file, base/fapi_ft.c. There are errors problems defining them, so clang doesn't recognize FF_stream_read, FF_stream_close, etc. when it proceeds anyway.

I think ​https://github.com/macports/macports-ports/pull/8747 would fix this, but wonder if this ticket should just be closed as duplicate of #61306.

[kencu (Ken)]

Yeah - looks like a combo of things in the end -- the freetype update did indeed break all ghostcript builds on all systems, as figured, but there are also other errors that relate to xcode12 specifically that needed other fixes.

fun, fun, fun :>

AIUI this wasn't specific to Xcode 12 and so this new ticket wasn't really needed.

part was , part wasn't
