[cfe-dev] clang++ linker issues on Ubuntu AMD64.

[Lang Hames]

Hi Török,

I should have been more clear on this detail too: My "empty" file contained
an empty main function, rather than being completely empty. So the issue
with the "missing" main is due to the main symbol being named ":main"
instead of "main".

- Lang.
