license   
qnx is using gcc as backend then it supposed to include some libraries in binaries, and I believe gcc's license is gpl 
so QNX should open source for these too? Or QNX rewrote these libraries?

The GNU tools src (gcc, gdb, binutils etc) is available in the Core development tools project. Is this what you are 
referring to?

There's also libgcc.a (runtime support lib for gcc) - the source for this is in the gcc directory in the src above. 

Or are you referriing to something else?

QNX is using gcc as a compiler, does not mean the binary comes out of gcc is linking with GPL'd library. QNX provide 
their own libc to keep the "clean IP". 

And of cause, just because you "used gcc", doesn't mean you have to open source your binary. The source of "gcc" (as 
well as other GNU utils) that QNX used, is opened.

Btw, the QNX libc is also part of the core os source that "opened for public access" (sorry, read too much slashdot 
comments) yesterday.

Re: license   
libgcc.a is what I am referring to.
as an example: QNX binary A staticly linked with QNX' libc.a(or dynamically linked with libc.so), libgcc.a,  if you 
don't open source for QNX binary A, is that a problem? I assume libgcc.a is GPL'd.

libgcc has a special excemption that says that if you linnk it against something, that something does not have to be 
distributed under the terms of the GPL:
