## Ideally, we would like to use Libtool for producing, and linking with,
## object files from C codes.  That means any C source code
## explicitly included in OpenAxiom, or produced internally by a Lisp
## compiler.  However, the SYSTEM calls by GCL on Windows is very tricky
## to convince to properly resolve path names to executables.
## Consequently we temporarily give up here, e.g., we don't
## instruct GCL to use Libtool on Windows.

## Again, ideally, we would like GCL to link with the compiled Lisp
## code from core.lisp.  However, the general interface compiler::link
## that GCL provides for that task is unsupported on Windows platforms.
## So, we instruct GCL so load the source file instead.
