[alsa-devel] [PATCH 2/3] configure.in: Add m4 check for new AM_SILENT_RULES

[Stefan Schmidt]

From: Stefan Schmidt <stefan at slimlogic.co.uk>

Kbuild like output for automake (>=1.11). It's no hard dependency as it needs
the newest automake, but enable it by default if it is available. To turn it off
you can either use --disable-silent-rules at configure time or make V=0  at
compile time.
