Dynamic link

The Dynamic Link module enables Nelson to build, load, and call C/C++ and Fortran code at runtime.

It supports generating gateways, loaders, and managing shared libraries for integration with external compiled code.

By default, Nelson does not try to detect a C/C++ compiler on Windows. Do not forget to run 'configuremsvc' or 'configuremingw' once.
