1949 # a .DEF file, then linker will be run (through gcc) against them to
1950 # build a shared library consisting of all given .o files. All libraries
1951 # (.a) will be first decompressed into component .o files then act as

1953 # which will be put into .DLL. To see the list of accepted options (as well
1954 # as command-line format) simply run this program without options. The .DLL
1955 # is built to be imported by name (there is no guarantee that new versions
1956 # of the library you build will have same ordinals for same symbols).
