Here are the files.

Notice that about half of the size of the MSVC object file is taken by debug
information ("/Zi" option was used when compiling it) while all gcc versions
contain no debug information at all. More details about the file contents can
be obtained using dumpbin Microsoft utility which I'd be glad to run for you if
you don't have it. Here is just an overview for now:
