These additional options are available on System V Release 4 for compatibility with other compilers on those systems:
Create a shared object. It is recommended that -symbolic or -shared be used instead.
Identify the versions of each tool used by the compiler, in a
.ident assembler directive in the output.
Refrain from adding
.ident directives to the output file (this is the default).
Search the directories dirs, and no others, for libraries specified with -l.
Look in the directory dir to find the M4 preprocessor. The assembler uses this option.
