Here's my workaround

#ifdef __GNUG__
		streambuf sb;
		sb.setbuf(definition, strlen(definition)+1);
		istream in(&sb);
#else
                istream in(strlen(definition) + 1, definition);
#endif

	... stuff deleted

This seems like it should do the trick, but I'm just in the
middle of trying to build iv 3.0 myself, so use this advice
with caution.

Hope this helps,

Roger
