Now that System V Release 2 also supports long variable names (and hooray
for that!), this warning should be reiterated - long variable names are
*very* nice, but if you want your software to run on most of the UNIX
machines out there, keep them unique in the first 6 characters.  On the
PDP-11, even S5R2 has the 7-character limitation.
