That would be brilliant, thanks. In Fedora wine is the last thing that
depends on lcms(1) and it would be great to be able to retire the
package in F20.

As I understand it, the icm defines are now lcms defines in lcms2.h,
i.e. a simple sed script should fix those up.

Wine still exposes the handle, what are you doing with the header that
requires access to the struct? I added a few setters/getters recently,
and I'm sure Marti would be open for some more if there's a use-case.

Right. I assume WCS is a V2 only workflow, or does it do V4 too?
