I agree with the intent of this bug but third party code doesn't
generally include <krb5/foo.h> because this has been a standard
mistake in Kerberos distributions for over a decade.  We decided
to put a number of ancilliary files from Heimdal into /usr/include/krb5
but by default Heimdal doesn't, it just installs them into the
include directory directly.

Now, that said, this is unlikely to be a problem because we do have
/usr/include/krb5.h and we have modified it and all of the other
includes to include <krb5/foo.h> and so little would end up breaking
if we made this change.

This raises another issue that has bothered me about krb5-config
which is:

        $ krb5-config --libs
        -L/usr/lib -lkrb5 -lhx509 -lcom_err -lcrypto -lasn1 -lwind -lroken <
        -lcrypt -lpthread

that it asks applications to directly link against all of the
Kerberos libraries rather than just -lkrb5.  In a dynamic world,
libkrb5.so will pull in all of the other libs---asking applications
to directly link against them unnecessarily makes the names of all
of the support libraries part of the ABI.
