Okay, I narrowed down the "excess arguments to m4_pushdef" to the following  
tiny case:

AC_INIT([crystal], [1], [someone])
AC_ARG_ENABLE([cpu-specific-optimizations],
    [AC_HELP_STRING([--enable-cpu-specific-optimizations=level],
        [foo, bar])],
    [], [])
AC_OUTPUT

It turns out that AC_HELP_STRING is the culprit.  If I remove the comma from  
[foo, bar], then the error disappears.  I suspect that the quoting in the  
new definition of AC_HELP_STRING in 2.57d is not working correctly when it  
calls the newly introduced AS_HELP_STRING.
