create a typedef for the function argument to mkd_string_to_anchor, because some

compilers (and by some compilers, I mean "gcc") whine bitterly when you pass a
function argument with with a more specific pointer in place of a void*.   And if
I can't trust the compiler to emit sensible warnings, I'll just cast the damned
argument to a type that makes it stfu.

In addition, I needed to add prototypes for the html5 tag adder and the two
functions that spit out a list of the flags that the code was compiled with.
