1991 # build a shared library consisting of all given .o files. All libraries

1994 # which will be put into .DLL. To see the list of accepted options (as well
1995 # as command-line format) simply run this program without options. The .DLL
1996 # is built to be imported by name (there is no guarantee that new versions
