Well, the rejection of newer FontForge versions *is* founded!  For
example, I've just tried to compile lilypond with the current git
version of fontforge, and I get *zillions* of fontforge error messages
like

  Internal Error (overlap) in timesig.C44:
    Winding number did not return to 0 when x=415.356
  Internal Error (overlap) in scripts.reverseturn:
    Fixup error 2 in MergeIntersections.
  Internal Error (overlap) in clefs.G:
    monotonic is both needed and unneeded
    (350.004,1194.21)->(363.013,1189.42). y=1190.08 (prev=370.968)

while processing lilypond's music fonts.

In most cases those errors are serious, making the glyphs unusable.

While the fontforge development team tries to improve the GUI and
usability, which is a noble goal, they completely fail to restore the
robust overlap removal code as present in 20120731.  George Williams's
heritage is quite heavy, since his code is hard to understand...

My conclusion: We have to stay with fontforge 20120731 to get working
lilypond fonts.
