No, I've decided against it, because it gets ugly, and I have better things= to do than try to fix systems that were already EOL when I last used Windows myself (which is a *long* time ago). Libstdc++ is just going to officially and explicitly say that prehistoric versions of Windows are not supported when using the win32 thread model. Ei= ther use the posix thread model (which makes use of winpthreads), or build for non-prehistoric versions. So that might mean that GDB needs to pick a newer default value of _WIN32_WINNT, because the current "define it to 0x0501 if not defined alrea= dy" logic selects a prehistoric version which cannot be used with GCC 13 + --enable-threads=3Dwin32 Sorry, but libstdc++ progress is not going to be held back by a tiny handfu= l of vocal users that aren't actually helping provide support for their dead targets. --=20 You are receiving this mail because: You are on the CC list for the bug.=
