scsh-0.3 on AIX

[hhw0@gte.com]

I encountered two (small) problems compiling/installing scsh-0.3 on
AIX v3.2 with gcc C library 2.6.0:

1. The file scsh/syscalls.c contains prototype definition
      symlink(const char* ... )
   is in conflict with my library definition
      symlink( char* ... )
  And so is the truncate(...) definition in the same file.
   Workaround: commented out the prototype definitions in syscalls.c

2. Macro HAVE_TZNAME is not defined.
   
   Workaround: modified Makefile so that
     DEFS= -D....  -DHAVE_TZNAME

If you have a better fix, please let me know.
Otherwise installation is smooth.  Many thanks for the nice software.
