State-Changed-From-To: analyzed->feedback
State-Changed-By: bkoz
State-Changed-When: Fri Jun  8 16:05:28 2001
State-Changed-Why:
    Should be fixed with:
    
    	libstdc++/2992
    	* include/std/*: Add copyright notice.
    	* include/c_std/bits/*: Use using statements instead of extern "C".
    	* include/c_std/bits/std_cmath.h: Don't overload double versions
    	of math functions with __buitin versions, use global version to
    	prevent ambiguities. Remove define hacks.
    	* include/c_std/bits/std_cwchar.h: Using declarations for "C"
    	functions that have changed signatures and std::
    	declarations. Remove define hacks.
    	* include/c_std/bits/std_cwchar.h: Same, plus remove ambiguous
    	__builtins in std::. Remove define hacks.
    	* testsuite/17_intro/headers_c.cc: Add tests.
    	* testsuite/17_intro/headers_c++.cc: Add test.
    
    
    I'll check this into branch and head shortly.
    
    Thanks!
