MIDI Generation Broken

[Will Oram]

Following the upgrade to 2.9.16, two things have regressed that (at  
least for me) break lilypond. One is a tie-related heisenbug that I  
can't pin down at the moment (ties aren't generated as expected,  
which tends to throw off lyrics), so I'll stick to MIDI generation  
problems.

Since 2.9.16, I have not been able to create a single MIDI file from  
code. No one else has this problem? If one uses the same sample code  
from http://lists.gnu.org/archive/html/lilypond-user/2006-08/ 
msg00415.html , this error appears:

8creation.ly:105:8: error: syntax error, unexpected "\\tempo"
\midi {
        \tempo 8 = 158 }

Actually, I'll duplicate the code from the link above, with a few  
improvements to make it easier on the eye.
