Using and Porting GNU CC - System V Options

Options for System V

These additional options are available on System V Release 4 for compatibility with other compilers on those systems:

-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.
