cpython/Modules/Setup.config.in

# This file is transmogrified into Setup.config by config.status.

# The purpose of this file is to conditionally enable certain modules
# based on configure-time options.  Currently thread support and
# garbage collection support are the only two modules so enabled.

# *NOTE*: if the configure script decides it can't support threads,
# the thread module will still be enabled and cause compile errors.
# The solution is to use --without-threads on platforms that don't
# support threads.
@USE_THREAD_MODULE@thread threadmodule.c

# Garbage collection enabled with --with-cycle-gc
@USE_GC_MODULE@gc gcmodule.c
