I'm pretty sure it is not a C thing and that nothing is mentioned in
the standard.

From Apple's own docs:

"The name of a symbol representing a function that conforms to standard C calling conventions is the name of the function with an underscore prefix. Thus, the name of the symbol representing the function main would be _main."

    <http://developer.apple.com/documentation/DeveloperTools/Conceptual/MachOTopics/Articles/executing_files.html>

I'm pretty sure it's just Mac thing.

It's not. I learned of this long before I switched to using a Mac.
