His name is Klaus-Peter Gulden (gulden@chemie.uni-wuerzburg.de).

Receiving the March 95 version of GAMESS, it was necessary to remove one
of the latest modification done by Mike ;-) (I replaced all occurences
of DREAL to DBLE
by adding few lines in the "hack" part of the comp script). It was not
mandatory,
but I also added an fdate function to zpcunix.c. I've sent these
modifications
to Mike, but I don't know if these hacks were included in the newer
distributions or not.

Note: 
1. the DREAL --> DBLE hack is not necessary if you use g77 instead of
f2c+gcc
2. none of the g77 compiler versions were able to produce a usable
_optimised_
   (i.e -O2 or -O3 compiler switch used) code of GAMESS for my AMD
5x86/133 CPU
   (which is actually a fast 486 chip), so I still prefer to use f2c
(the situation
   may be different with the Pentium CPU).
