+From: Thomas Sondergaard <Thomas.Sondergaard@mi.medical.canon>
+Date: Thu, 4 Jan 2024 17:45:46 +0100
+Subject: [PATCH] meson: Use check_header to confirm headers work
+
+instead of using has_header use check_header to confirm the header
+works. This is necessary to get the meson build to work with Visual
+Studio 2022. It has <stdatomic.h> but it does not actually work when
+compiling a C program. A minimal C program that include <stdatomic.h>
+fails with the following errors:
+
+    C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Tools\MSVC\14.38.33130\include\vcruntime_c11_stdatomic.h(36): error C2061: syntax error: identifier 'atomic_bool'
+    C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Tools\MSVC\14.38.33130\include\vcruntime_c11_stdatomic.h(36): error C2059: syntax error: ';'
+    C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Tools\MSVC\14.38.33130\include\vcruntime_c11_stdatomic.h(37): error C2061: syntax error: identifier 'atomic_char'
+    C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Tools\MSVC\14.38.33130\include\vcruntime_c11_stdatomic.h(37): error C2059: syntax error: ';'
+    ...
+    ...
+
+check_header is consistent with CMake's
+
+    check_include_file(stdatomic.h  HAVE_STDATOMIC_H)
+
+which is why the CMake-based build of dbus works with Visual Studio
+2022, while the meson build doesn't.
