Hijacking this thread originally about
https://fedoraproject.org/wiki/Changes/Autoconf_271
What is the current thinking in Fedora about always running
"autoreconf -i" during builds that use autotools?
1) "autoreconf -i" is not enough. It needs to be executed "autoreconf -fi" and to have proper visibility reconfigure issues should be executed "autoreconf -fiv"
2) Looks like still no one performed experiment of rebuilding all existing packages with %configure macro in spec by execute:
$ for i in *.src.rpm; do rpmbuild --rebuild -D "_configure 'autoreconf -fiv; configure'" $i; done
To check which Fedora packages are failing in the build environment with autoconf 2.71.
