[riot-devel] RIOT and static initializers in C++

I was just reading and wondering, would it be easier just to drop main as
the application name?

So long as it is well documented it shouldn't make a huge difference to the
user.
And that way the toolchain should take care of all the initialization it
needs to.

Cheers,

Ryan
