New issue 1595 by percival.music.ca: lilypond-book papersize gives margin  
warnings
http://code.google.com/p/lilypond/issues/detail?id=1595

  Trying to compile the regtest added here:
http://git.savannah.gnu.org/gitweb/?p=lilypond.git;a=commit;h=66b49771545a61b591b529330797163ff42e2e8f
  (the commit message includes build instructions)
  produces
warning: systems run off the page due to improper paper settings, setting  
default values

  This happens from
lily/output-def.cc
  and it apparently referring to line width, left margin, and right margin.

The pdf output looks good-ish.  I mean, it looks good for the stuff I've  
tested it with, but I have no clue how large c9 actually is, nor whether  
we're losing margins or whatever.

It would be nice if somebody investigated this, although it's a bit tricky  
-- the problem may lie in lilypond-book, or in the scheme internals, or the  
initial values in scm/, etc.
