    Map .hin files to the C language for doxygen
    
    In Debian unstable, the current version of doxygen is unhappy with
    our generated Doxyfile, and does not handle krb5.hin in the expected
    fashion (as a C header).  Work around this issue by explicitly
    specifying that files with the .hin extension are to be treated
    as C language files.
