[Bug libstdc++/106908] libsupc++ wrong declaration of __unexpected_handler
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106908 --- Comment #2 from ralphengels at gmail dot com --- ah my bad then i just thought it looked suspicious especially since i been having problems building gnat. For some reason it tries to link to the static libgcc library and aborts due to an exception. So i had to change the GCC_LINKER_FLAGS to force -shared-libgcc. so when i spotted this i assumed a typo might have occured breaking the exception handlers.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83562 ralphengels at gmail dot com changed: What|Removed |Added CC||ralphengels at gmail dot com --- Comment #4 from ralphengels at gmail dot com --- This still is not working causing several boost libraries to fail building when using mingw-w64 compilers (gcc-9.3 and gcc-10.2). Everything works fine with the 64 bit compiler but the i686 compiler reports broken TLS. While we can get around it by disabling the TLS check for libbost_fiber-mt.dll libboost_stacktrace_windbg_cached-mt.dll is another story (halts the build if we skip the TLS check).

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67114 --- Comment #19 from ralphengels at gmail dot com --- Had problems with the define not being pulled in from os_defines.h (i think a better place would have been gthr_posix.h since that gets pulled in at build time) hence the change, also if using another posix thread implementation it would break using that instead since your define would then be undefined leading to a build error. Besides that better implementations are welcome :) this was just an example of a possible fix.

[Bug libstdc++/67114] [MinGW64] build failure with POSIX threads enabled
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67114 --- Comment #20 from ralphengels at gmail dot com --- Clarification. If not using pthreads-w32 #ifdef PTW32_VERSION // See libstdc++/67114 # define _GLIBCXX_THREAD_ID_LESS(X, Y) ((X).x < (Y).x) <- this #endif would end up undefined if say we build with winpthreads. As you noticed yourself os_defines.h gets pulled in after gthr.h so it fails, my suggestion if using a macro would be to put it in gthr_posix.h instead. My reason for this suggestion is that gthr_posix.h gets linked to gthr.h when building with posix threads and is visible to all parts of the code. My patch was made for the mingw.org compiler, since they still use pthreads-w32. Hope this clears it up, i was a little tired at the time of writing my last reply.

Im also running into this problem in stage2 where it fails to find stdarg.h. As an experiment i tried reverting kai's work but it still fails to find system headers. A non bootstrap build works but im having problems with programs using libstdc++. All programs compiled that depends on libstdc++ will crash with initialization error 0xc05. My machine is Win7 64. All previous gcc versions build fine btw. And work also. I have tried with versions compiled by other parts and the problem persists.
