I am not exactly an expert here, but .o is what GNU compilers (GNAT is
the GNU Ada compiler) usually produce. .obj is usually produced by
compilers on the Microsoft platform.

MSVC isn't able to link .o files, but it is possible to use GNAT to link
all your files to a DLL. The GNAT linker can read .o *and* .obj files.
How to create DLLs with GNAT is described in the GNAT User's Guide.
