[Pkg-alsa-devel] Bug#343555: alsa-source: fails to configure with bash 3.1 as /bin/sh

[Aaron M. Ucko]

Package: alsa-source
Version: 1.0.10-2
Severity: grave
Justification: renders package unusable

alsa-source's config script fails on my system (which has bash 3.1-1
installed as /bin/sh); AFAICT, the problem is constructs such as

	ALSA_NOPNP="$(. /etc/alsa/alsa-source.conf >/dev/null 2>&1 ; echo "$ALSA_NOPNP")"

which bomb out with status 127 because ifndef is not a command and the
subshell evidently inherits the -e flag.  Given that this worked okay
with previous versions of bash, and also works with dash, that may be
a bug in bash 3.1; however, I'd still suggest avoiding trouble by
prepending "set +e; " to the list of commands for all three variables.
