libraries including other libraries; hierarchies

Couple questions; first:

In my top level jamfile, I have:

project jamroot : requirements <toolset>gcc:<cxxflags>"-pedantic" ;

How can I do a double-condition:

project jamroot : requirements <os>NT:<toolset>gcc
:<cxxflags>"-pedantic" ;

or should I be doing this using if/else statements? Specifically, I'm
trying to differentiate between MinGW and gcc-linux.

Next question:

If I have the following hierarchy:

src/
src/math
src/math/vector
src/math/matrix
src/demo

How can I get the src/math/jamfile to include both subprojects and
unify them into one library without adding the sources of vector and
matrix specifically? That is, if vector and matrix along the lines
of:

lib vectorlib : vector.cpp : <link>static ;
lib matrixlib : matrix.cpp : <link>static ;

I'd like to have src/math/jamfile as:

lib math : vectorlib matrixlib : <link>static ;

When I try this, I'm getting undefined references; that is, I have
something like:

exe demo : demo.cpp ../math//math ;

and vector.cpp, matrix.cpp aren't being compiled (thus trying to use
them is undefined reference).
