Bug: Unresolved `makedev` symbol when compiling with `cosmoc++`

[edubart]

What happened?

The following example fails when compiling with C++.

#include <sys/sysmacros.h>
int main(){return makedev(1,2);}

Workaround is to use extern "C" {} when including the header <sys/sysmacros.h>, or compile as C code.

Version

cosmocc (GCC) 14.1.0

What operating system are you seeing the problem on?

Linux x86_64.

Relevant log output

cosmoc++ a.cpp -o a
