V2 questions

Greetings all,

I have a few more questions regarding using Boost.Build V2:

[1] (I'm pretty sure this is a GCC setup problem): Compiling/Linking a 
simple Hello world app, I get

[begin]
gcc.link ..\..\code\hello\bin\gcc-3.0\debug\hello.exe
..\..\code\hello\bin\gcc-3.0\debug\hello.o: In function `main':
/cygdrive/d/devel/ADL++/code/hello/..\..\code\hello\hello.cpp:6: undefined 
refer
ence to `cout'
/cygdrive/d/devel/ADL++/code/hello/..\..\code\hello\hello.cpp:6: undefined 
refer
ence to `ostream::operator<<(char const *)'
/cygdrive/d/devel/ADL++/code/hello/..\..\code\hello\hello.cpp:6: undefined 
refer
ence to `ostream::operator<<(char)'
collect2: ld returned 1 exit status

g++ -g -o "..\..\code\hello\bin\gcc-3.0\debug\hello.exe" 
"..\..\code\h
ello\bin\gcc-3.0\debug\hello.o" -Wl,-Bdynamic -Wl,-Bstatic -Wl,-Bdynamic

...failed gcc.link ..\..\code\hello\bin\gcc-3.0\debug\hello.exe...
[end]

I have GCC 2.95.3-5 installed at root (d:/devel/cygwin) and it worked fine 
until I build and installed GCC 3.0 (to /usr/local). I'm pretty sure this is 
to do with the version of libstdc++.a being linked -- which is why I wanted 
to link $gcc-dir/lib/libstdc++.a (this solved the problem before. Does 
anyone know whats wrong?

[2] How do I link external libraries (e.g. urlmon.lib) to an executable?

[3] Is it possible to perform specific actions on a target? E.g. move an exe 
to a specific directory once built? Or run a target? Or specify an action 
set, e.g.:

action-set finalize :
<action>move
<action>run
;

exe hello : hello.cpp
:
<bind-action>finalize
;

Regards,
Reece
