In version 9.00, there exists a directory Resource/Font which contains the standard URW Type 1 fonts with long names. However, a directory Resource/AFM which holds the corresponding AFM files is missing. Why? While I agree that gs itself doesn't need AFM files, they are nevertheless an intergral part of the Type 1 fonts IMHO. I strongly suggest to add the AFM files again.
We don't want to distribute files that are not needed for running Ghostscript. The URW fonts are a separate distribution (with different file names) and these do have .afm files in case applications use them. I really don't think applications use, or trust, AFM files anymore since so many fonts don't have them and the move is to TT and OpenType fonts.
