A bit of a hacky patch to remove some old Heimdal conditional code and build with gcc-4.6
The -r1 ebuild includes a new patch in mod_auth_kerb-5.4-s4u2proxy-r1.patch. This uses MIT kerberos specific calls which break the build against Heimdal. I have attached a new version of the patch which should address this issue.
http://osdir.com/ml/encryption.kerberos.heimdal.general/2006-10/msg00085.html was used as a hint for writing Heimdal compatible code.
I do not have MIT installation to confirm that the change works both ways.
