Comment (by thorkilnaur):

 Since I am unable to test the Windows part of this patch, I have split off
 the Windows-related part of the patch and attached it to a new ticket:
 #1140. The Mac OS X-related part of the patch (attached file openal-mac-
 os-x-part-1.patch) has been tested with success on a PPC Mac OS X 10.4.
 The difference in the configure output before and after applying the patch
 is summarized here:

 {{{
 829a830,832
 > checking build system type... powerpc-apple-darwin8.6.0
 > checking host system type... powerpc-apple-darwin8.6.0
 > checking target system type... powerpc-apple-darwin8.6.0
 839,840c842,985
 < checking for library containing alGenSources... no
 < configure: WARNING: no OpenAL library found, so this package will not be
 built
 ---
 > checking how to run the C preprocessor... gcc -E
 ...
 > checking value of ALC_CAPTURE_SAMPLES... 786
 845d989
 < config.status: include/HsOpenALConfig.h is unchanged
 847d990
 < config.status: include/HsOpenAL.h is unchanged
 }}}

 The patch has also been tested on a (SuSE) Linux system to ensure that
 OpenAL is still detected. For Linux, the difference between the configure
 output before and after applying the patch is less marked, as we would
 expect:

 {{{
 834a835,837
 > checking build system type... i686-pc-linux-gnu
 > checking host system type... i686-pc-linux-gnu
 > checking target system type... i686-pc-linux-gnu
 983d985
 < config.status: include/HsOpenALConfig.h is unchanged
 985d986
 < config.status: include/HsOpenAL.h is unchanged
 }}}

 I should stress that the above test has only served to ensure that OpenAL
 after the change is detected and that the OpenAL package is then being
 built. The functions of the OpenAL package have not been tested.

 Based on this, I recommend that the attached patch openal-mac-
 os-x-part-1.patch is applied and the ticket closed. Ian, please ...?
