Which clang version is this?
This is clang 17.0.0:
$ gcc -v
Apple clang version 17.0.0 (clang-1700.0.13.3)
Target: x86_64-apple-darwin24.4.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
I didn't try GCC 14 before (I was focusing on GCC-13). Under GCC 14, it's
immediate showing that the "(fixnum) conversion" patch will be required, beside
the "--disable-libboot" patch. I believe it will be a success (building not
finished yet).
I will also try more recent clang versions (18 - 20) because Apple will soon
adopt them in the next year.

I cannot give a precise summary on the building status of GCL 2.7 on both Apple
compiler and GCC-14 at this moment. A partial result is that
1) macOS 10.15 - 15 with Apple clang compiler, all work.
2) macOS 10.11 - 15 with GCC-13, all work. (Now I'm changing to GCC-14).
In earlier macOS versions (10.6 - 10.10), the blocking issue is that the system
call "readlinkat()" doesn't exist. If you can change configure.in to detect it
and fix the code when it's not available, then I believe GCL 2.7 can support
these older macOS versions too.
I will keep testing on different OS/compiler combinations and report any new
breakage. But overall speaking the situation on macOS x64 is very good now.
Thanks!
