I've received a report of a mingw build failure:
../../../gcc/libgcc/libgcov-interface.c: In function '__gcov_fork':
../../../gcc/libgcc/libgcov-interface.c:185:9: error: implicit declaration of

As far as I understand it, mingw doesn't have fork and doesn't declare
it in , so it's not clear to me how this has ever worked. I
would expect a linker failure. Maybe that doesn't happen because the
object containing a reference to fork is only ever

Hmm, so why's it then referenced and not "GCed"?
The classical "solution" is to make the reference weak via sth like
extern typeof(fork) fork () __attribute__((weak));
There are issues about weak symbols on mingw targets. Calls to weak functions c

This has nothing to do with garbage collection. It's just the way
libgcc avoids having too many source files. It would be exactly the
same if every function were in its own file.
