Why isn't a similar patch needed for lib/regex.c?
Can you determine the earliest version of Clang that supports both "#
pragma GCC diagnostic push" and "# pragma GCC diagnostic ignored
"-Wvla""? A quick glance at the archived manuals suggests it goes back
to at least Clang 4 but I suspect it's

Do you have any handy example of configure that takes too long to run?
Sure. Coreutils, emacs. Pretty much any nontrivial configure script
takes longer than it should.
I understand that parallelization of shell scripts is nontrivial.

If this hasn't happened, that might be becau

GRUB makes use of a built-in version of gnulib, but when attempting to build
it with clang, it is failing when building regex due to the use of
variable-length arrays.
There is a pragma that disables this when using GCC, but that is not enabled
when building with clang.
On the otherhand, clang a
The use of variable-length arrays (VLAs) is disabled by default in
clang 9 and above.
The same pragma that works for GCC also works for clang, so check for
clang 9+ too.

Thanks for the investigation. I cannot reproduce the issue, because I don't
know how you build your chroot environment. But anyway, with the details you
gave, I believe the following patch should fix the failure.
