Compilation of newly released GMP 6.3.0 on macOS (both Intel and ARM) leads to
wrongly compiled libraries, with a flat namespace. This is generally avoided
(and enforced by various build tools) on macOS since many OS versions, because
it can cause linker errors due to name collisions.
The reason for this is this hunk in the configure script:
darwin*) # darwin 5.x on
# if running on 10.5 or later, the deployment target defaults

This was generated by an autoconf, which relies on an outdated libtool version.
This was fixed in libtool by
https://git.savannah.gnu.org/cgit/libtool.git/commit/?id=9e8c882517082fe5755f2524d23efb02f1522490
(which is included in latest release, version 2.4.7).
Would it be possible to release the next version with more recent
autoconf/libtool combo?
Sorry about that. I knew there were problems with old autotools and
quickly tried updating them before the release, but that caused too many
problems. Since we wanted a release because of a number of other
improvements, it was safer to stick to the old ones (no worse than the
previous release). I hope we can update for the next release.
If a pro of autotools wants to give a hand...
