APPROVE COMMIT 21.5
I discovered that my autoconf test for ALSA was flawed.  The pcm.h
header depends on other ALSA headers, yielding errors during the
configure run.  This patch changes it to a header file with no
dependencies.
ChangeLog addition:
2006-03-27  Jerry James  <james(a)xemacs.org>
	* configure.ac: Repair ALSA detection.
