>Description:

	int main()
	{
		( int() > int() );
		return 0;
	}

gives:
	$ c++ t.cpp
	t.cpp: In function `int main()':
	t.cpp:3: parse error before `>' token

>How-To-Repeat:
	See code sample above. Also fails with user defined type default constructor calls. This was detected in a test harness that exercises comparison operators on default constructed objects - perhaps a similar test should be included in the compiler testsuite.
>Fix:
	Not a work around, but if the parenthesis around the offending expression are removed, the expression compiles as expected. In my case not feasable as the expression is mixed with i/o stream inserters.
