* doc/invoke.texi (-Wconversion): Document warnings specific to C++.
* c-common.c (convert_and_check): Move warning logic to...
(warnings_for_convert_and_check): ...here. Define.
* c-common.h (warnings_for_convert_and_check): Declare.
cp/
* cvt.c (cp_convert_and_check) : Define.
* cp-tree.h (cp_convert_and_check): Declare.
* call.c (convert_conversion_warnings): Rename to
conversion_null_warnings. The warning for floating-point to
integer is handled by convert_and_check in convert_like_real.
(convert_like_real): convert_conversion_warnings was renamed as
conversion_null_warnings.
* typeck.c (build_binary_op): Use cp_convert_and_check to warn for
overflow and changes of value during conversion.
testsuite/
* g++.dg/warn/Wconversion-integer.C: New
* g++.dg/warn/Wconversion-real.C: New.
* g++.dg/warn/Wconversion-real-integer.C: New.
* g++.dg/warn/conv2.C: Updated.
