2.9.22 eps backend on Windows

[Bertalan Fodor]

I think it's a bug:

I'm trying to use the eps backend (also by lilypond-book) and it doesn't
work. I get the following error:

Can't find (or can't open) font file c059013l.pfb.
Can't find (or can't open) font file 
c:/Prog/LilyPond/usr/share/ghostscript/8.50/Resource/Font/CenturySchL-Roma.
