Original commit message from CVS:
Fix differences between configure.in and configure.ac which were trivial
or due merely to formatting differences. diff can now be used to see only
the significant differences, which should be helpful in keeping these
two files in sync.
Original commit message from CVS:
Simplify alsa checking: we can use the standard AM_PATH_ALSA macro to
check that we don't have alsa 0.9.x: we just need to specify something
for ACTION_NOT_FOUND to override the default AC_MSG_ERROR behaviour, so
I've put a colon for ACTION_NOT_FOUND. ;-)
Also, update the alsa macro in acinclude with the latest from the alsa
project CVS.
