As per summary.
The currently-masked alsa-lib version has a midi useflag that I introduced to
reduce the size of the library itself. When this useflag is disabled (the
default is enabled), the snd_seq_* functions won't be in the library. The
snd_seq_* functions are needed by dosbox to be able to compile:

I'm attaching an ebuild patch for 0.70 that adds the (almost standard now)
check for the midi useflag on alsa-lib.
Thanks,
Diego
