Great. If you have the time and energy, could you take a look at the tons of fixes made by Pierre Muller (for OpenBSD among others)?
Too generic. But I have looked at rtl/openbsd and most seems to be merged, except for a few that I merged now.
I had one t_bsd related openbsd fix on my list and mentioned it to Florian. Probably the t_ and i_ files will have to be checked using logs or diff since I don't track/split out compiler revisions for the most, so sb else has to do that.
It would help tremendously, if you simply try to build and compile some test programs with fixes_3_2 in your openbsd setup. The merge window is still at least two weeks, so there is time for such things.
