When building the standalone example with llvm, the link step fails:
examples/standalone/libstubs.o: In function `dummy': include/_exports.h:10: undefined reference to `jt' include/_exports.h:11: undefined reference to `jt' include/_exports.h:12: undefined reference to `jt' include/_exports.h:13: undefined reference to `jt' include/_exports.h:14: undefined reference to `jt' examples/standalone/libstubs.o:include/_exports.h:15: more undefined references to `jt' follow
Indeed, the standalone libstubs.o does use the jt symbol, but it was marked 'static' in stubs.c. It's strange how gcc builds are working.
