Problems with alsa mixer code - uclibc/buildroot related?

[Adrian McMenamin]

I am having serious problems with compiling my driver for the sound card
on the Dreamcast now I have added some very basic mixer code.

Compilation fails reporting the unavailablity of various types declared
in asound.h - though I know this header is included (via more than one
route).

Scanning through the header reveals nothing obvious - like a stray
#ifdef that might exclude SH4 - so I just want to check through all the
angles: is there any reason to think this might be uclibc/buildroot
realted - verbose output from the build is below.

The code compiled fine until I added the *very* basic mixer code
(essentially just place holders for the mixer functions).
