If you are so focussed on the exitcode, I think simplest is having both. One focusses on errorlevel, and one that really always runs the shell.

Depending on the codebases that you run, you select the variant that gets the system() identifier. Or make it an alias even depending on a define in the header. (like #ifdef unicode in windows headers)

And document it very, very thoroughly.
