[tex-k] luatex font bug: "checksum mismatch" warnings on64bitsystem

[Akira Kakuto]

FYI, C versions of ovp2ovf, ovf2ovp, opl2ofm, ofm2opl were probably
written by John Plaice or his students in order to replace corresponding
ones written by using the WEB. There are no man pages for them.
Sometimes bugs were found in them compared with the WEB ones.
Peter fixed a number of bugs. However the WEB versions still remain for the
safety by prepending 'w'. There may be few users today of Aleph/Omega,
however the utilities are still conveniently used, for example, to create
virtual fonts in (u)pTeX.

Thanks,
Akira
