That seemed to provide some useful information;  Here is what my cygwin 
command line output shows.  MKS korn shell shows the same:

gcc version 4.5.3 (GCC)17: in module scope from module

bash-4.1$

So I the the g++ executable doesn't seem to be found under bjam while under 
the shell it's available via the $PATH

The relevant part of my user_config.jam is:

# Configure specific gcc version, giving alternative name to use.
# using gcc : 3.2 : g++-3.2 ;
using gcc : : g++ :
    <linkflags>-Wl,--enable-auto-import
    <linkflags>-Wl,--enable-stdcall-fixup
;

the site_config.jam is the default from the release version.

I've also tried variations of toolset=g++, toolset=g++-4, etc without any 
success.
I"ve also tried setting the user_config to various things like

using gcc: 4.5.3 : g++4 ;
using gcc: 4.5.3 : g++ ;

etc.

Any suggestions appreciated.
