Then you can try extracting LD.EXE from the built package, without installing it using `pacman -U`. > don't mind creating another completely separate mingw-64/gcc-8.1 > installation under MSYS2 which works natively under Windows if > necessary, as long as it contains the fix.

As mentioned above, you can always extract `.tar.xz` packages by hand and I don't think there is any difference. > Also when doing things within MSYS2 am I opening > the MSYS2 MSYS prompt or am I opening the MSYS2 MingW 32-bit or MSYS2 > MingW 64-bit prompts ?

The system roots for these subsystems are '/usr', '/mingw32' and '/mingw64' respectively. `makepkg-mingw` should be run in a MSYS2 shell to prevent unexpected interference of 32 and 64 bit programs, but I haven't tried running it in a MinGW32 or MinGW64 shell. Honestly I build packages mostly in CMD (I only ever tried building something in the MSYS2 shell a couple of times). -- Best regards, LH_Mouse
