what do I do? what is the blessed way of writing an integer literal with the value of INT32_MIN? (without creating a special case for INT32_MIN)

@typeswitch suffix it?

@dysfun is there a macro for picking out the correct suffix for fixed-size integer types? 🤔

@typeswitch shrug i doubt it. but you can use a long and let it truncate?

@dysfun looks like INT32_C(...) should work, hope it exists in VC

@dysfun nope, that doesn't work. I think i'll just special case INT32_MIN and INT64_MIN. 🙃

For INT32_MIN the LL suffix would work but I think INT64_MIN is going to have the same problem and there's no suffix that'll work there.
