That explains why it had no effect for you.

Take a look at a tutorial regarding the GNU Build System, e.g. [1].

To regenerate a configure script, run 'autoreconf' in the source directory.
When you do this, also do a 'make distclean' in the source directory,
and remove all build directories in which you ran '../configure ...'

To "make distclean" when no Makefile is there, run
  make distclean
This is the most reliable way to remove leftovers from previous builds.
