I am in a 64 bit MSVC dev shell, but need to run 32 bit ML / MASM.

So I added this to my bat file

"C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.38.33130\bin\Hostx86\x86\ml" /nologo -c %LIBPCCDIR%\_ftol.asm

And this is what happens

C:\work\pcc-revived\pcc\os\win32>"C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.38.33130\bin\Hostx86\x86\ml" /nologo -c ..\..\..\pcc-libs\libpcc\_ftol.asm
