[Bug c++/30945] New: iostream includes excessive headers - results in large files

[rosenwad at bxscience dot edu]

On Bjarne Stroustrup's site, it's says in the FAQs:

________________________________
Why is the code generated for the "Hello world" program ten times larger for
C++ than for C?
It isn't on my machine, and it shouldn't be on yours. I have even seen the C++
version of the "hello world" program smaller than the C version. When I
recently (2004) tested using gcc -o2 on a Unix, the two versions (iostreams and
stdio) yielded identical sizes. There is no language reason why the one version
should be larger than the other. It is all an issue on how the implementor
organized the libraries. If one version is significantly larger than the other,
report the problem to the implementor of the larger.
__________________________________

Perhaps unnecessary files are being included in <iostream>. These files should
NOT be over 400 KB. In fact, a standard Win32 header compiles to a smaller
file.

Really this is nothing to do with header files really.  
I think the FAQ is wrong with respect to the C++98 standard as he forgets there
are locale supported added which brings in a lot.

Also including iostream, forces the initialization of the C++ standard streams.

Let's consider this simply a duplicate of 28080. I'm improving the situation a
bit, but don't expect miracles ;)
