Hi,
some time ago we bumped to gcc14, I remember a long discussion. I had no
issues at a first glance on my systems. MDD G4, MB i386 and MB x86-64.
Apparently on my MacBook i386 e.g. gcc 7 works, just used it today
However, today on MacBook x86-64 I was trying out various compilers with
a stubborn port and got issues (xz-boostrap) things got weird.
gcc-6 or gcc-7 appear to be excecutable, but end in a libgcc maze.
Look:
Artax:~ multix$ gcc-mp-7
gcc-mp-7: fatal error: no input files
compilation terminated.
Artax:~ multix$ gcc-mp-6
gcc-mp-6: fatal error: no input files
compilation terminated.
but if I use gcc7:
Artax:~ multix$ sudo port -vp upgrade xz-bootstrap
configure.compiler=macports-gcc-7

seems like a cycle of libcc versions.
Port outdated doesn't anything related:
The following installed ports are outdated:
mesa 22.1.7_2 < 24.3.2_0
sqlite3 3.48.0_0 < 3.49.0_2
xz-bootstrap 5.6.3_0 < 5.6.4_0
(all packages with compile issues)
