Subject: autoconf: Add support for setting PYTHON_PATH or NO_PYTHON
X-Git-Tag: v1.4.3-rc1~276^2~14
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=eb858c56cb9dcced05d61d47c0351b4f8768d379;p=git.git

autoconf: Add support for setting PYTHON_PATH or NO_PYTHON

This patch adds support for setting either PYTHON_PATH or NO_PYTHON to
autoconf generated ./configure script via --with-python=PATH (sets
PYTHON_PATH) or --without-python (sets NO_PYTHON).  Autodetect
PYTHON_PATH via AC_PATH_PROGS.
