Microsoft's compiler supports an extension for 128-bit literals. This is referenced in `intsafe.h` which is included transitievly. When building with modules, the literal parsing causes a failure due to the missing support for the extension. To alleviate this issue, support parsing this literal, especially now that there is the BitInt extension. Take the opportunity to tighten up the code slightly by ensuring that we do not access out-of-bounds characters when lexing the token.
