Use something like this:
// Test case, wrongexport.cpp
// g++ -shared -fPIC -o /tmp/libwrong.so wrongexport.cpp -fvisibility=hidden
// nm -DC /tmp/libwrong.so | grep Astruct # misses AStruct in gcc!!!
#define

Unfortunately I've not a minimal test case for this, but in gjs we can't use
pre-compiled headers with g++ (while they work fine with clang++).
In particular, we get

This is crazy, as even according to strace the file isn't there...
But it is and it's valid.

Ouch, I forgot to delete an include after pasting
# Works
g++ -I _build main.c -o

It's also relevant to say that just using
main.c:
#include "gjs_pch.h"
int main(int argc, char**argv)
{
std::string s = "Hi";
return 0;
}
fails with:
❯ g++ -I _build main.c -o main -include string

Well, I see...
At least the error should be a bit clearer though.

I see the point, but then I also think that gcc-10 should not support
`--std=c++20` option but rather only the `--std=c++2a` one.
