You're running the C compiler (cc1) here, not the C++ one (cc1plus), because
you've passed a file with the plain .c extension to the driver.

So it doesn't have this global variable that only exists in cc1plus.
Either change your test file to .cpp, or add "-x c++" to the command-line.
In general, as long as your plugin refers to global_namespace directly, it's
not going to be compatible with any of the other language sub-compilers apart
from cc1plus. If you wanted it to work with any kind of language, I think
you'd need to look up global_namespace using dlsym (and handle the case when
it was not found), rather than linking against it directly.
