From 45e83f865876e42d22cf4bc242725bb4a25a12e3 Mon Sep 17 00:00:00 2001 From: Bernd Edlinger Date: Mon, 6 May 2024 07:07:07 +0200 Subject: Fix build issues with mingw toolchain With a x86_64-pc-mingw32 toolchain there is a build issue whether or not the --disable-threading option is used. The problem happens because _WIN32_WINNT is defined to 0x501 before #include which makes the compilation abort due to missing support for __gthread_cond_t in std_mutex.h, which is conditional on _WIN32_WINNT >= 0x600. Fix the case when --disable-threading is used, by only including in gdb/complaints.c when STD_CXX_THREAD is defined. Additionally make the configure script try to #include to automatically select --disable-threading when the header file is not able to compile.
