"we cannot assume that we have fontforge 20110222
with --enable-double until ../configure checks for this.
This requires a change to configure.in which will be 1-10 lines of
code."

I don't know how to check for --enable-double but this patch assures
that fontforge 20110222 is a requirement, not an option.
