On mac the unmangled symbol is not being visible at the time of linking

Somethings has changed in Rust (Mac) in the last month that is affecting how the symbols get exposed in the generated static library. When I compile my kernel on Linux things work fine. However on mac - the libkernel.a that gets generated under the kernel directory does not seem to contain the "cmain" symbol - which is clearly there in kernel.rs

Just realized that I did not provide the path - https://github.com/ckkashyap/unix

I believe that this is just an artifact of platform differences. On OSX symbols get a leading underscore where on Linux they don't:

# on OSX
$ rustc foo.rs && nm -g libfoo.rlib
libfoo.rlib(foo.o):
                 U ___morestack
0000000000000000 T _foo

# on linux
$ rustc foo.rs && nm -g libfoo.rlib

foo.o:
0000000000000000 T foo
                 U __morestack

As a result I'm going to close this as not a bug.
