Are you sure it broke ? Isn't it so that is just runs happy along with want
you told it ?

It works the following way:
* if you don't give an argument, it will autoprobe
* if you just give --with-krbN, it will autoprobe
* if you give --with-krbN=/path/here, it will use /path/here/{include,lib}
    without asking any stupid questions.
* if you give --without-krbN, it will not use krbN

Forgot that, thanks, added it with a twist to the cvs-repository.

configure in generated by configure.in + aclocal.m4.

aclocal.m4 is generated by aclocal (the program) + acinclude.m4 + all test
in -I argument to aclocal.

See the file HACKING and autoconf info pages.

If you just want to try you patch (that will work) just enter the commands
in HACKING (you'll need autoconf 1.4 and autoconf 2.13 (or never))
