The autoconf Python interpreter search was slightly modified to search for Python even if $PYTHON is set to an empty string. This is done by unsetting PYTHON if it is set but empty, then following the usual macro.
This was required since
export PYTHON
in a Makefile will create thePYTHON
variable but will assign it no value (i.e. empty string). This causes issues in some build environments.The backup
configure~
script was also added to the developerac-clean
cleanup rule.
