Your patch *is* correct -- it's just not the whole story.  I think we
still want it -- there are places that we need to check whether the
name is `main' without the declaration.

I thought about this -- the C++ front-end has DECL_MAIN_P.

Perhaps.  

I'd prefer to let front-ends set this bit as they see fit, though.
For example, in some languages, the main function might be called
`start'.  The DECL_ASSEMBLER_NAME for such a function might be `main'
to allow the C start-up code to work, but DECL_NAME might not be
`main'.

I'd sugget we apply your patch, and then think about how to solve this
best.
