compile: link dynamic OR static library in Windows

[Richard (Rikki) Andrew Cattermole]

On other platforms the -Lfile I think would work.

On Windows you have to link against the import library not DLL directly.

You can pass it to the compiler:

$ dmd -i "-L/LIBPATH:C:\Program Files\PostgreSQL\15\lib" pq.lib app.d

Should work. Sorry, I should have revisted this from the get go, rather 
than just tinkering with what others were posting.
