Hello, pytest, a popular Python testing tool/framework, uses files named conftest.py for its configuration. OTOH many autoconf macros run "rm -f conftest*", clobbering conftest.py in the directory where ./configure lives. In our case at least, it's the topmost directory. I tried naive things such as setting up a trap to restore conftest.py from a backup copy on EXIT (and other signals) in configure.ac, using AC_CONFIG_FILES to restore it from a backup copy, but apparently there are more "rm -f conftest*" which still succeed to delete it. How this be helped, short of running ./configure in a wrapper which would restore the file after ./configure is run? Thanks, Dima
