Subject: Cleanup of the Makefile system.
X-Git-Tag: v3.0.0~1^2~16
X-Git-Url: http://mj.ucw.cz/gitweb/?a=commitdiff_plain;h=3b75e19aae5e7d9da0754134aaad211cdf8f60d2;p=pciutils.git

Cleanup of the Makefile system.

Parameters of the configure script are passed from the top-level Makefile
in environment variables. DNS support has been made a regular build option
with an attempt at its auto-detection.
