This was the standard config that comes with boost. However I am just 
trying to run the configure script. I changed cross_compiling to yes 
inside of the configure script tell the script that I am cross 
compiling. Is there a better way to do this? I renamed /usr/include of 
my cygwin installation to something different, so that configure won't 
find it. Then I run configure with the following environment variables:

export PATH="$PATH:/cygdrive/c/QNX630/host/win32/x86/usr/bin"
export CXX="qcc"
export CXXFLAGS="-I/cygdrive/c/QNX630/target/qnx6/usr/include"
export LDFLAGS="-L/cygdrive/c/QNX630/target/qnx6/x86/lib 
-L/cygdrive/c/QNX630/target/qnx6/x86/usr/lib"
./configure

The output is as follows:

***

This unfortunately doesn't generate a user.hpp! Maybe this is correct. 
So I went on to compile boost. First I compiled bjam for cygwin and 
executed it with the arguments below. This seems to compile the sources 
correctly but doesn't link. I guess the build system thinks it is 
building the library for Windows and that's the reason for suffixing the 
library with .dll and passing parameters like --enable-auto-image-base. 
So is there a way in gcc-tools.jam to explicitly tell the build system 
to build the libraries for Unix?

Thanks in advance!
