SimGear change. It changes all the SG_xxxx to be the 'real' includes, and gets
rid of many #ifdef SG_HAVE_STD_INCLUDES. As an added bonus, rather than
replacing 'SG_USING_NAMESPACE(std)' with 'using namespace std', I just fixed
the small number of places to use std:: explicitly. So we're no longer polluting
the global namespace with the entire contents of std, in many cases.
There is one more 'mechanical' change to come - getting rid of SG_USING_STD(X),
but I want to keep that separate from everything else. (There's another
mechnical change, replacing <math.h> with <cmath> and so on *everywhere*, but
one step at a time)
If there is a windows problem, look very carefully at the line termination
with a serial port monitor. It should be \r\n (CR-LF), not \n, not \r\r\n
or any other possible variant.
format. I have a Garmin 295 to test with, but so far I haven't been able
to make this work (code should compile cleanly though.) I don't know if
I've made a mistake in the protocol or if my 295 just doesn't support this.
More work on this to come.
