Thanks for noticing this definition. Yes, it was added to enable proper types in mingw/mingw-stdint.h for AArch64. Based on the review, TARGET_64BIT has been excluded from aarch64/aarch64-coff.h, and mingw/mingw-stdint.h has been modified to support AArch64.

Does some code that is shared between x86 and aarch64 rely on this definition? It might be worth identifying the code in a comment if so. Thanks, Richard
