# The following rpath_flag setting code is distilled from MIT Kerberos'
# src/config/shlib.conf.  Some of this seems ancient and likely to be
# wrong in some cases, but right for all the cases we probably care
# about.  Also, this will very likely be wrong depending on how the
# caller will be doing link-edits (with what compiler-driver or
# link-editor)!  There's no fixing this.
#
# In principle this doesn't belong here: application should instead use
# krb5-config --libdir to get the directory to use for the rpath, then
# workout the rpath flags on their own.  Of course, there's no --libdir
# option...  And MIT's krb5-config does include rpath flags.
#
# Compatibility with MIT is the winning consideration for now.
