    AX_GNU_AUTOTEST: quote some static strings
    
    Some static strings in AC_SUBST() were underquoted: fix that.

    AX_PROG_DOXYGEN: quote DX_RULES
    
    Quote the DX_RULES assignment to prevent some other M4 macro from
    modifying the text. Also transition from direct if-statements to AS_IF
    for the same reasons: to prevent undesired macro replacements.

    AX_VALGRIND_CHECK: fix logic around AC_CHECK_PROG
    
    There are two problems in the logic around the first AC_CHECK_PROG()
    call:
    
    1. If AC_CHECK_PROG() fails to find valgrind, with neither configure
       option --enable-valgrind nor --disable-valgrind, then the
       enable_valgrind variable ends up being set incorrectly to yes.
    
    2. If configure was started with --disable-valgrind, then there is no need
       to run AC_CHECK_PROG() at all.

    AX_VALGRIND_CHECK: clean up configure message
    
    When running configure, the displayed text contained two interleaved
    messages. Got:
    
    checking whether to enable Valgrind on the unit tests... checking for 
valgrind... valgrind
    yes
    
    instead of the probably intended:
    
    checking whether to enable Valgrind on the unit tests... yes
    checking for valgrind... valgrind
    
    In addition, the first message seems to convey no additional information
    compared to the second message: if valgrind is not found (and there is no
    --enable-valgrind error), then the result of the check is "no" as
    displayed for the executable check. And in all other cases, the result is
    "yes". So remove the first message completely: this takes care of the
    mangled status messages.
