1975 # a .DEF file, then linker will be run (through gcc) against them to
1976 # build a shared library consisting of all given .o files. All libraries

1979 # which will be put into .DLL. To see the list of accepted options (as well
1980 # as command-line format) simply run this program without options. The .DLL
1981 # is built to be imported by name (there is no guarantee that new versions
