On Windows 32-bit platforms (Win95 and WinNT) the standard object
file format is COFF, however, COFF does allow for "optional headers"
and corresponding sections which can contain implementation specific
information. The Microsoft VC++ compilers use the .debug section
with an IMAGE_DEBUG_TYPE set to either COFF or CODEVIEW.
For the most part there is no problem linking MS object files with
GNAT generated object files. I've never seen a problem when using
the MS linker, but 'ld' can still have some problems with some of
the oddball MS files (certain types of C++ stuff I believe).
