mzc usually uses ld to link instead of gcc. For Unix linking, the
command line that mzc builds for ld works just as well for g++, but
that's not the case for Windows.

Adding "++ldl -lstdc++" instead of "--linker ...g++.exe" to the mzc
command line may fix the problem. Or you may have to add more libraries,
such as "++ldl -stdc++ ++ldl -lc". Or even more.

For example, I managed to link a Cygwin-compiled tree.obj using the

 mzc --ld tree.dll ++ldl -lstdc++ ++ldl -lc 
  ++ldl -Lc:/cygwin/lib/gcc-lib/i686-pc-cygwin/3.2/ ++ldl -lgcc
  ++ldl -lcygwin ++ldl -lkernel32
