Hi folks,

Following Even’s merge of part 1 a few days back, I’ve opened a merge request for part 2: !205 <https://gitlab.com/libtiff/libtiff/-/merge_requests/205>

This consolidates all the remaining changes proposed a couple of weeks back into a single change. The details are on the MR description, but I’ll copy them here too for reference:

This is part 2 of the C99 conversion work. Following discussion on the mailing list, this combines steps 2 and 3 of the original proposal. Rather than transitioning to using the C99 types via a temporary set of tiff_-prefixed types, this does the transition in a single step.

The one bit I’m not convinced by is the “legacy-types” option at configure time. It adds additional complexity and variability to a libtiff installation which might cause more problems than it’s worth, especially when you can just compile with the “TIFF_LEGACY_TYPES” macro for the same effect. If there are no objections, I’d like to drop this part.

The change is quite large, but the vast majority of it is the renaming of the types with no code changes to speak of. The remainder is mostly the update of the Autoconf and CMake logic to enable C99 and remove the legacy type checks.

Any comments much appreciated either here, or on the merge request if it’s for comments on the specific changes.

Kind regards,

Roger
