org-compatible-face

org-compatible-face is a compiled Lisp function in `org-compat.el'.

(org-compatible-face INHERITS SPECS)

Make a compatible face specification.
If INHERITS is an existing face and if the Emacs version supports it,
just inherit the face. If INHERITS is set and the Emacs version does
not support it, copy the face specification from the inheritance face.
If INHERITS is not given and SPECS is, use SPECS to define the face.
XEmacs and Emacs 21 do not know about the `min-colors' attribute.
For them we convert a (min-colors 8) entry to a `tty' entry and move it
to the top of the list. The `min-colors' attribute will be removed from
any other entries, and any resulting duplicates will be removed entirely.
