"PCRE2 support is not installed: %s", dlerror());
/* So here's something weird: PCRE2 actually renames the symbols exported by the library via C
* macros, so that the exported symbols carry a suffix "_8" but when used from C the suffix is
* gone. In the argument list below we ignore this mangling. Surprisingly (at least to me), we
* actually get away with that. That's because DLSYM_ARG() useses STRINGIFY() to generate a string
* version of the symbol name, and that resolves the macro mapping implicitly already, so that the
* string actually contains the "_8" suffix already due to that and we don't have to append it
* manually anymore. C is weird. 🤯 */
