Comment (by kencu):

 I have been trying to show that gcc builds gmp incorrectly when using the
 standard linker too, just like clang does...

 but no matter what I do, I can't seem to force gcc14 to use the standard
 linker. It always uses ld_classic, eg:
 {{{
 libtool: link: gcc-mp-14 -O2 -pedantic -fomit-frame-pointer -m64
 -mtune=nehalem -march=nehalem -o .libs/t-toom6h t-toom6h.o
 ../../tests/.libs/libtests.a /Users/cunningh/gmp-6.3.0/.libs/libgmp.dylib
 ../../.libs/libgmp.dylib
 ld: warning: -ld_classic is deprecated and will be removed in a future
 release

 }}}

 I thought gcc had been changed recently to no longer use ld_classic --
 that is what the commits said

 https://github.com/macports/macports-
 ports/commits/master/lang/gcc14/Portfile

 but there have been some fixups and refixups in gcc and I"m not sure just
 now what it is doing.

 what I do know is that these gcc14 versions:
 {{{
 % port -v installed gcc14 libgcc14
 The following ports are currently installed:
   gcc14 @14.2.0_3+stdlib_flag (active) requested_variants=''
 platform='darwin 23' archs='x86_64' date='2024-09-30T22:25:34-0700'
   libgcc14 @14.2.0_3+stdlib_flag (active) requested_variants=''
 platform='darwin 23' archs='x86_64' date='2024-09-30T22:25:29-0700'
 }}}

 which are current, are using ld_classic as above.
