In reality libgcc also depends on the thread library, as C does have a little construction in the language which is not implementable by the library. It is `_Thread_local` in C11 which is equivalent to the longstanding GCC extension `__thread`. The configure flag to inform GCC to use winpthreads is `--enable-threads=posix`. -- Best regards, LH_Mouse _______________________________________________ Mingw-w64-public mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/mingw-w64-public
