Two corrections have been made in the IDL mode for Emacs (idl.el).

Fixes in version 1.41:

* JD Smith <jdsmith@astrosun.tn.cornell.edu> corrected a bug in his 1.39 fix:
  In the fontification (colorization) of IDL object code, in some cases 
  only two letters after the "::" were fontified correctly.

* Due to incomplete version checking, Emacs 20 was calling code intended
  for Emacs versions 19.29 and less.

The recent versions of idl.el and idl-shell.el are supplied at:

    ftp://pivory.mpae.gwdg.de/pub/idl/emacs/
http://pivory.mpae.gwdg.de/idl/emacs/
http://www.mpae.gwdg.de/mpae_RZ/software/idl/emacs/

I do not have enough Emacs Lisp knowledge to maintain these modes.
If you do, please contact me.

Best regards
Kevin
