Dunno much about Borland. With gcc you can link directly to the dll:

gcc -o my_app.exe my_app.c -LC:\location_of_libgmp-3_dll -lgmp-3

Will that work with Borland compilers ?

If it doesn't, then you'll have to build an import lib and link to that. If
you don't know how to create an import lib from the dll using Borland then
maybe ask about that on an appropriate forum.

Or try Google. Googling for  'Borland import library' turned up which suggested that you can
build an import library from the dll by running:

  impdef libgmp.def libgmp-3.dll
  implib libgmp.lib libgmp.def

I'm not sure if 'impdef' and 'implib' are Borland tools - you might have to
Google for them, too. In any case, that was the first (and only) link I
visited - you might find other solutions if you spend some time searching.

Once you have built the import lib (libgmp.lib) you should be able to build
your GMP app by linking to that import lib.
