[v3] stdexcept, more tests

[Benjamin Kosnik <bkoz at redhat dot com>]

I believe this to be the last of this set...

2001-02-27  Benjamin Kosnik  <bkoz@redhat.com>

	* include/bits/std_stdexcept.h (runtime_error): Make string
	member non-const.
	(logic_error): Same.
	* testsuite/19_diagnostics/stdexceptions.cc (test04): Add test.
	(test03): Fix.
