Thanks Tom and Martin,

Thats almost cleared up this for me.

Thank you both for your explaination (very helpful); question?  The C++
standard library is linked by default with gpp.  How does this manifest
itself - I dont mean where is the C++ library, but rather how is it linked?
Is it compiled into a binary or can I define its location (add config
switches) in a config file? Basically I should think that the linker error
can be amended.  I want to avoid having to add extra suff to the compiler
line when excuting cmd line compiles e.g. gpp test.cc -o test.exe.

Regards,
