4.15 tcsh - an alternative shell

tcsh is available from <ftp://ftp.deshaw.com/pub/tcsh>
Compiles with no problems. You must edit /etc/security/login.cfg to
permit users to change to this shell (chsh), adding the path where the
shell is installed (in my case, /usr/local/bin/tcsh).

Under AIX 3.2.5, you need to modify the "config.h" file, changing
    #define BSDSIGS
to
    #undef BSDSIGS
