Description:
The current build of lilypond don't work at all.
Looks like it's a bison 3.0 related bug, see: http://lilypond.1069038.n5.nabble.com/bison-3-0-fix-lilypond-td148774.html


Additional info:
* package version: 2.16.2-4
* Here's the output with any file:
GNU LilyPond 2.16.2
Processing `test.ly'
Parsing...
/usr/share/lilypond/2.16.2/ly/chord-modifiers-init.ly:26:3: error: syntax error, unexpected REAL
<
c e gis>1-\markup { "+" }
/usr/share/lilypond/2.16.2/scm/chord-entry.scm:116:16: In procedure ly:pitch-transpose in expression (ly:pitch-transpose root (ly:make-pitch 1 0 ...)):
/usr/share/lilypond/2.16.2/scm/chord-entry.scm:116:16: Wrong type argument in position 1 (expecting Pitch): 1

* Tentative fix:
I got a working build by adding this to the prepare() statement of the PKGBUILD:
# Fix build with bison-3.0
rm lily/out/parser.*


Steps to reproduce:
Try to compile any file. Same with an empty file
$ touch test.ly
$ lilypond test.ly
