python311 @3.11.8 has on PPC Leopard, Mac OS X 10.5.8, an unsupported PEP 11 support tier: powerpc-apple-darwin9.8.0/gcc

[ballapete (Peter "Pete" Dyballa)]

The configure script produces this output:

configure checking for PEP 11 support tier... configure: WARNING: powerpc-apple-darwin9.8.0/gcc is not supported

and when finishing:

configure: WARNING:

Platform "powerpc-apple-darwin9.8.0" with compiler "gcc" is not supported by the
configure CPython core team, see https://peps.python.org/pep-0011/ for more 

The compiler used is GCC7. it's only a warning, and I have no idea what PEP 11 support is good for, but there is some danger that things can fail – I for example cannot build Python modules from source, see #69106, #69319, or #69320.

Just saw two more warnings:

ld: warning: 32-bit absolute address out of range (0x1002151BC max is 4GB): from _usedpools + 0x00000004 (0x002151C4) to 0x1002151BC
ld: warning: 32-bit absolute address out of range (0x1002151BC max is 4GB): from _usedpools + 0x00000000 (0x002151C4) to 0x1002151BC

The hex value 0x1002151BC is decimal 4,297,150,908, 4 GB is decimal 4,294,967.296, 2,183,612 too much. Later, similarly:

ld: warning: 32-bit absolute address out of range (0x10023A1CC max is 4GB): from _usedpools + 0x00000004 (0x0023A1D4) to 0x10023A1CC

And once more:

ld: warning: 32-bit absolute address out of range (0x10022E190 max is 4GB): from _usedpools + 0x00000004 (0x0022E198) to 0x10022E190
ld: warning: 32-bit absolute address out of range (0x10022E190 max is 4GB): from _usedpools + 0x00000000 (0x0022E198) to 0x10022E190

There is also unnecessary use:

Isn't termcap a relic from last millennium?

PEP 11 defines the support tiers for cpython. Not something that can be changed in a port.
