ok, latest cvs, and hopefully ive doing this from clean sources (it worked 
last nite at least), but my build now fails at the final link due to ALSA 
issues ...

$ ./configure --enable-alsa
...
checking for dmedia audio support... no
checking for ALSA CFLAGS... 
checking for ALSA LDFLAGS...  -lasound -lm -ldl -lpthread
checking for libasound headers version >= 0.9.0... found.
checking for snd_ctl_open in -lasound... yes
-- /usr/lib/libasound.so.* -> libasound.so.2
-- /usr/lib/libasound.so.* -> libasound.so.2
checking for dlvsym in -ldl... (cached) yes

...

the reason for the duplicate definition is that SDL_alsa_audio.lo is listed 
twice in the call to `libtool --mode=link -o build/libSDL.la` ... and this is 
because SOURCES="" is fed ./src/audio/alsa/*.c twice in configure ...
