It doesn't matter where the header files are. gcc/g++ will automatically find
all of the header files it is supposed to find.
gcc will NOT automatically find any C++ header files (like iostream) but g++
will.
The header style was changed to conform with the C++ standard. I'm not 100%
of the reasoning behind the change, though.
You can access the system headers either with or without the .h in both g++
and MSVC++. g++ gets progressively more strict about C++ compliance as each
version is released, though, so it's harder to go the non-standard route. As
somebody mentioned, if you *really* need to keep the .h (and I don't know why
you would unless you are also compiling the code on a very old compiler), you
can enable it with newer g++ with -Wno-deprecated
