Hello. I think https://github.com/python/cpython/pull/23142 changed the behavior of distutils.sysconfig.parse_makefile().

A downstream Fedora report with an affected petsc package: https://bugzilla.redhat.com/show_bug.cgi?id=1959088


Reproducers (DeprecationWarnings removed for readability):


$ cat makefile
ALL: lib

DIRS = ssls asls # isls rscs
LOCDIR = src/tao/complementarity/impls/

include ${PETSC_DIR}/lib/petsc/conf/variables
include ${PETSC_DIR}/lib/petsc/conf/rules
include ${PETSC_DIR}/lib/petsc/conf/test


$ python3.9
>>> from distutils.sysconfig import parse_makefile
>>> makevars = parse_makefile('makefile')
>>> makevars.get('DIRS','').split()
['ssls', 'asls']

$ python3.10
>>> from distutils.sysconfig import parse_makefile
>>> makevars = parse_makefile('makefile')
>>> makevars.get('DIRS','').split()
['ssls', 'asls', '#', 'isls', 'rscs']



And:

$ cat makefile
-include ../../../../petscdir.mk
ALL: lib

include ${PETSC_DIR}/lib/petsc/conf/variables
include ${PETSC_DIR}/lib/petsc/conf/rules
include ${PETSC_DIR}/lib/petsc/conf/test

$ python3.9
>>> from distutils.sysconfig import parse_makefile
>>> makevars = parse_makefile('makefile')
>>> makevars.get('DIRS','').split()

['cr', 'bcgs', 'bcgsl', 'cg', 'cgs', 'gmres', 'cheby', 'rich', 'lsqr', 'preonly', 'tcqmr', 'tfqmr', '\\']
