On a pmax (ELF):

	mona:pc532/floppies/inst 54# cc -v -E - < /dev/null
	Using builtin specs.
	gcc version egcs-2.91.60 19981201 (egcs-1.1.1 release)
	 /usr/libexec/cpp -lang-c ... -D__NO_LEADING_UNDERSCORES__ ...
	mona:pc532/floppies/inst 55# nm /usr/src/bin/cat/obj.pmax/cat | grep -w main
	0040079c T main

I don't know if __NO_LEADING_UNDERSCORES__ applies to other ELF ports
