Esix directory(3c) functs broken on non-sysv ffs

[Scott E. Garfinkle]

Like the title says.  Doing an opendir/readir to loop through
a directory doesn't get all the entries.  This is a problem in libc.a and
also libc_s.a.  You will discover, for example, that the shells can't 
find run yacc, even though 'ls -l /usr/bin/yacc' works.  I have reported
this to Esix, but I get the impression that it's going to be a low-priority
to fix.  Anyway, workarounds are either to give up long file names or
to replace the entries in libc.a with the (better) PD versions of these
functions.  If you do that, get the Gnu binutils, etc., so that ls, etc., work.
As for csh, it will work properly (more or less) if you issue the 'unhash'
statement in your .cshrc so that csh explicitly tries every possible
directory for your executables.  (Or you can use another shell.)
