For an example of a dynamically-linked extension implemented in C++,
see plt/collects/mzscheme/examples/tree.cxx. This is a fairly ambitious
example, because it makes the C++ class act like a Scheme class.

Other examples in that directory are written in plain C, and mostly
bind Scheme functions to call C functions.

To statically link code into DrScheme (MrEd really), you could modify
Makefile.in in plt/src/mred/ or the MSVC project in plt/src/worksp/,
then probably modify "mred.cxx" to call your setup code at the end of
setup_basic_env(). But I recommend a dynamic extension, instead.
