Missing links to the URW+ fonts in 8.64's fontmap

[Ludovic Courtès]

Hello,

With GNU Ghostscript 8.64, I noticed the following:

--8<---------------cut here---------------start------------->8---

The problem stems from the fact that links to the URW+ PFB files
disappeared from `Fontmap.GS' sometime between 8.62 and 8.64.

I solved it in the NixOS distribution with this patch:

  <URL:https://svn.nixos.org/websvn/nix/?op=comp&address@hidden&address@hidden>

Do you confirm that this is the right approach?

Thanks,
Ludo'.

PS: address@hidden' seems to be swallowing emails without ever
    publishing them and without sending any kind of notification to the
    sender.  Perhaps a misconfiguration?
