   4 # Unless explicitly requested by the user (e.g.
   5 # "./configure --bundled-libraries=!asn1_compile") this will always use the
   6 # bundled Heimdal, even if a system heimdal was found. The reason
   7 # for this is that our checks for the system heimdal are not accurate
   8 # enough yet to know if it is usable (some bug fix might be missing,
   9 # compile_et might not generate the expected code, etc).
