Fix for C++23 standard library module usage. #326

Closed stripe2933 closed 7 months ago

stripe2933 commented 7 months ago

Currently argparse cannot be built using ARGPARSE_MODULE_ENABLE_STD_MODULE macro, because there are two problems.

In argparse.hpp, the header <cerrno> should be outside the macro if statement because errno macro variable cannot be exported via C++ module.
In argparse.cppm, to use <cstdlib> features, std.compat module should also be imported.

This PR's commits include these fixes.
