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.
of rolling our own unset.
(_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
in practice we needn't worry about CDPATH if unset doesn't work.
Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
apparently treats PATH="nonexistent" as if it contained ".".
