3.14.17: 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.
