configure and alsa on Fedora Core 2

Hi all,

I found a bug in the ./configure script that comes with
ogle-0.9.2.tar.gz:

I am using Fedora Core 2 with a custom build kernel (2.6.7-rc3) and ran 

$ ./configure --enable-alsa=yes --disable-oss

The alsa version that comes with the 2.6.7 kernel is 1.0.3 but the
configure script disabled the alsa because it couldn't find a version
0.9 or higher:

  checking for alsa version... found 0.5.x
  configure: WARNING: Disabling ALSA support, install a 0.9.x version

I couldn't quite figure out what the configure script was doing exactly,
but eventually I commented out the version checking (see below). After I
did this, ogle successfully compiled (with alsa) and ogle worked fine
(with sound).

My 2cts in tracking down the problem:

configure looks for sys/asound.h. This does exist (in /usr/include) but
is a depreciated header and only contains an #include <alsa/asound.h>.
The <alsa/asound.h> also only contains #includes, one of which is
<alsa/version.h> - this header contains the SND_LIB_MAJOR and
SND_LIB_MINOR version information. I was wondering if the configure
script is smart enough to jump from <sys/asound.h>, via <alsa/asound.h>
to <alsa/version.h> to egrep the SND_LIB_MAJOR etc. Or perhaps the
version info before alsa 1.0.x used to be in sys/asound.h?

regards and thanks for a nice and simple player,

PS what I commented out in the configure script (don't forget the "#fi"
at the end):
