As long as you have a reasonably recent version of omniidl, there is a
-k flag which prevents comment stripping, so you can do

  omniidl -E -k foo.idl

to pre-process foo.idl without stripping comments. omniidl does its
pre-processing by forking omnicpp which is actually GNU cccp under
another name. You can run it directly with the -C flag to keep
comments.

Cheers,

Duncan.
