I don't think <library> is an accepted option for
using gcc.  It's certainly not listed here:
http://www.boost.org/build/doc/html/bbv2/reference/tools.html#bbv2.reference.tools.compiler.gcc
Also, '\' is an escape character.
You should probably use <linkflags> with -L.
I'm actually a bit surprised that MinGW doesn't handle
the paths automatically.
