The short answer is: Yes!

The long answer is that here have been three different issues around OSS
on current versions of FreeBSD where out of the box Wine would not build.

1. Lack of AFMT_FLOAT

   This has been addressed by Wine commit
     bed73e9e736ef2376e762730a30ad5f2611f969c
   of mine which only uses this if present.

   I also filed the following report against FreeBSD:
     http://www.freebsd.org/cgi/query-pr.cgi?pr=157050

2. Lack of AFMT_S24_PACKED

   This has been addressed by Wine commit
     051b64b66f82801d43016068639468575dc3974e
   of mine which replaced it with AFMT_S24_LE.

   I have not filled a bug against FreeBSD since according to
     http://manuals.opensound.com/developer/AFMT_S24_PACKED.html
   this does not appear all too useful to begin with?

3. Lack of SNDCTL_DSP_HALT.

   This is addressed by my latest patch that uses the equivalent,
   but older and deprecated, SNDCTL_DSP_RESET in case.

   I also submitted a patch against FreeBSD along the same lines:
     http://www.freebsd.org/cgi/query-pr.cgi?pr=156874 


As you can see, all three issues have been addressed in Wine now and
for two of them I filed bugs against FreeBSD (one with a patch). :-)

Thanks for your guidance and support around this!
