BBv2 trivially unusable (for me)

Maybe someone can shed some light. What I'm trying to do should be
simple. The problems are:

1. Project requirements in parent projects are not used in
child projects

2. The response to GCC compilation failures is not useful. Where
is the command-line of the failed invocation of g++?

3. Apparently it is attempting to build dependent targets (.exe,
.test) after their dependency (copy.o) has already failed to
build.

compilation fails when I build in
c:/src/osl/mtl4/libs/sequence/algorithm/test, as follows:

bjam gcc copy
...found 15 targets...
...updating 4 targets...
gcc.compile.c++ bin\copy.test\gcc\debug\copy.o

char**)' here

I still have problem 1 when I try to build with msvc:

bjam msvc-7.1 copy
...found 19 targets...
...updating 10 targets...

I have the following files:

c:/src/osl/mtl4/boost-build.jam:

c:/src/osl/mtl4/mtl4.jam: (not relevant to my problem, I think)
