Dear all,After several months of absence - my first manual build surprised me by the addition of the -qalias=noansi.
Before I open an issue - maybe it is not that important - I am trying to find what brought it in. It looks to be a change in behavior in configure(.ac) - starting with Python3.9.
Historical builds - and make.out: py38-3.8.7/.buildaix/make.out:0 py39-3.9.0/.buildaix/make.out:239 py39-3.9.1.0/.buildaix/make.out:254 py39-3.9.1/.buildaix/make.out:148 py3a-3.10/.buildaix/make.out:244 Prior to Python3.9xlc_r -c -DNDEBUG -O -I/opt/include -O2 -qmaxmem=-1 -qarch=pwr5 -q64 -I/opt/include -O2 -qmaxmem=-1 -qarch=pwr5 -q64 -I../src/py38-3.8.7/Include/internal
i.e., the flags became:xlc_r -c -DNDEBUG -O -I/opt/include -O2 -qmaxmem=-1 -qarch=pwr5 -q64 -I/opt/include -O2 -qmaxmem=-1 -qarch=pwr5 -q64 -qalias=noansi -qmaxmem=-1 -I../src/py38-3.8.7/Include/internal
Note the flags have been repeating themselves for a long time, but now - after the repeated flags `-qalias=noansi -qmaxmem=-1` is being added. my gut repsonse is that I do not like seeing 'noansi' being passed as a flag to the compiler and I am trying to understand why - also how.
Fyi: using `git log` I have tried to get any clue re: CFLAGS_NODIST and/or -qalias=noansi - but I do not seem to be skilled enough to find that information.
Help is appreciated - and, thereafter, as needed, I'll open an issue. Regards, M Felt aka aixtools
