Your working example below compiles without error using gcc 2.95.x (FreeBSD
4.x) and gcc 3.2.x (FreeBSD 5.x), which is expected since it's compliant
C++. (See Stroustrup's The C++ Programming Language, section 9.2.2, which
indicates that the proper way to include C++ standard library headers such
as iostream, string, etc. is using angle brackets and no dot-h.)
Be glad that the gcc maintainers have finally updated their C++ compiler to
be more standards-compliant.
I'd suggest feeding back patches to the jdk maintainer.
