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