Log Message:
mksh R38c contains the following fixes:

    *  [tg] Fix regression tests on OSes insisting on a shebang (Cygwin)
    *  [Sean Boudreau] QNX 6.4.2 ed(1) is said to have the bugs fixed
    *  [tg] Build.sh bugfixes: -DMKSH_BINSHREDUCED can also
        be given without -DMKSH_SMALL; allow HAVE_REALPATH=x and
        HAVE_REVOKE=x in the environment to re-enable these even if
        -DMKSH_SMALL disables them by default, like mknod already did
    *  [tg] -DMKSH_ASSUME_UTF8=0 skips the environment checks, like
        -DMKSH_ASSUME_UTF8=1, but disables the utf8-mode
    *  [tg] Apply some more KNF – style(9) – to the source; clean it up
        and further optimise for small size
    *  [OpenBSD] Fix segfaults caused by missing check for end of input
        in the tokeniser on “let --” and other input
    *  [OpenBSD] Make Vi editing mode ^W behave like Emacs mode’s
    *  [tg] If no killpg(3) is avaiable, use kill(2) and hope it works
    *  [tg] -DMKSH_NO_LIMITS skips trying to build the ulimit code
