Modified files:
        lib/m4sugar    : m4sh.m4 

Log message:
        (AS_SHELL_SANITIZE): Unset ENV, MAIL,
        MAILPATH and set PS1, PS2, PS4 to default values, to work
        around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
        For LC_ALL etc, first try to set to "C" as POSIX requires and as
        the Autoconf documentation specifies; fall back to "unset" only if
        this fails.  Use a shell for-loop for this rather than an m4 loop,
        to shorten the output script.
