Hi Harald,

indeed this might result in a bug if you pass a string that is freed a
little later. i.E. if you have something like 

void function(void)
{
    char test[] = "abcd";
    NutRegisterCgi(abcd);
}

This could IMHO fail. Even if this string is allocated in the data
segment as well, there is a little chance to missuse the function when
passing a local copy or a dynamicaly created string to NutRegisterCgi().

I implemented a short fix that makes a copy of the passed string before
saving it in the cgiFunctionList.

Provided ther is no reason contrary, I could check in my fix to CVS.

I also added a function to register a cgi-bin path other than cgi-bin/.
I could add this function as well.

Regards,

Ole Reinhardt
