Actually the man page is wrong, /usr/include/dbm.h and the source for
fetch in our dbm.c agree:

datum
fetch(key)
        datum key;
{
...
}

As for your problem, I think the fault is in rgb.c where the compiler
errs :-( . To wit --

pcc blows code generation for e.g. rgb.red = (red * 65535)/255,
emitting a divs.w. Forced assignement to a long to fix it. SCP.
