How to access assembly language symbols without a leading _ from C on 6502 (cc65)

Question

I'm writing some code in 6502 assembly language using cc65.

Because I'm living in 2022 and not 1979 and have access to a development machine that is a million times more powerful than the target platform, I'm writing unit tests for the assembly language code in C.

Obviously the calling conventions for C and assembly language are different, so I have a bunch of wrapper functions that accept C-style arguments and then call the assembly language functions.

But after calling an assembly language function, I want to check the state of various globals that are defined in assembly language, but I can't because C expects all identifiers to start with an underscore '_' and the identifiers in my assembly language modules don't.

I could just export every symbol twice, once with a '_' prefix and once without, but it seems so clunky and I just wonder if there's an easier way? Is there a #pragma or something that I can use to tell C to use the symbol name exactly as-is, without adding an underscore?

I've looked in the cc65 docs and found nothing, but it seems like a pretty common need, and I'm wondering what other people do.
