Yes, please. I am a novice at "configure" stuff. Can you do CMake too; if not, perhaps I can figure out what to do. Perhaps set up HAVE_ATTRIBUTE_UNINITIALIZED in config.h (because that is the same as other HAVE_s for the C system), and then define PCRE2_KEEP_UNINITIALIZED in pcre2_internal.h so it keeps the vector definition clean. Does that sound sensible? Thanks. I've just put out a Release Candidate for 10.35; I usually wait a month for comments before the real release, so it should be possible to get this patch in before than.
