A quick test case: In a C file, define `BitFlags` like: ```c typedef struct BitFlags { unsigned int _00 : 1; unsigned int _01 : 1; unsigned int _02 :...

ARM/AArch64 cross-compilation targets aren't respected in an MSVC environment on Windows.

In a fully set-up MSVC environment (e.g. an environment set-up by Visual Studio's `vcvarsall.bat`) with a target of AArch64 (`$Env:VSCMD_ARG_TGT_ARCH` == `arm64`) or ARM (`$Env:VSCMD_ARG_TGT_ARCH` == `arm`), LDC will set-up...
