+Subject: [PATCH] Force use of -ffreestanding when checking for gnumach headers
+
+Without this ./configure assumes that we are in a fully hosted
+environment, which might not be the case. After this patch, we can rely on
+the freestanding header files provided by GCC such as stdint.h.

+Subject: [PATCH] mach: Fix passing -ffreestanding when checking for gnumach
+ headers
+
+8b8c768e3c70 ("Force use of -ffreestanding when checking for gnumach
+headers") was passing -ffreestanding to CFLAGS only, but headers checks are
+performed with the preprocessor, so we rather need to pass it to CPPFLAGS.
