That's what it's supposed to do.  The expansion of a macro is subject
to re-expansion, so if you don't want the "main" in the macro
definition to itself be expanded, you have to quote it.
define(`main', `int `main'()')
And if you're worried that, e.g., "int" might also have a macro
definition, you could quote the whole definition:
define(`main', ``int main()'')
