commit r16-5306-g577c0f4a402bfb99d9770e3a90556a3946cb0e18 Author: Jason Xu <[email protected]> Date: Sun Aug 3 18:19:04 2025 -0400 gcc: Make aarch64-mingw32 target install wrap stdint.h Wrapped stdint.h for AArch64 MinGW32 is useful for bare-matal PE target e.g. UEFI, as those platform does not provide a system stdint.h, this would align with x86_64 mingw32 target which provides a wrapped stdint.h I have tested this by compiling a AArch64 UEFI Application using gcc's stdint.h, with -ffreestanding flag, and execute the application with AAVMF(edk2) inside QEMU. gcc/ChangeLog: * config.gcc (aarch64-*-mingw*): Set use_gcc_stdint to wrap.
