My plan was to switch to lcms2 soon *after* the release of Wine 1.6. I studied
the API some more and my conclusion is that while it doesn't have all we need
(specifically cmsReadRawTag and cmsWriteRawTag don't do what we want), we can
avoid importing the icc34.h header.

I'm not in favor of adding temporary workarounds. If distributions want to
drop support for lcms1 in 1.6 I'd suggest that they backport the patches.
