-P Produces preprocessed output in a file that has a suffix that is
defined by isuffix, isuffix_host, ixxsuffix, and ixxsuffix_host.
The default for host files is .CEX and for z/OS UNIX files is .i.
As with the -E option, the -C option can be combined with the -P
option to preserve the comments.
-S Produces an assembler source file for C source that is compiled
with the METAL compiler option. The -o option can be used to
override the default file name produced by -S. The default file name
is the C source file name with the suffix determined by the ssuffix
and ssuffix_host attributes in the configuration file.
-t Adds the prefix specified by the -B option to the designated
programs, where programs are:
v a (assembler)
v c (z/OS XL C/C++ compiler)
v L (Interprocedural Analysis tool - link phase)
v l (binder)

Note: This option must be used together with the -B option.
If -B is specified but the prefix is not, the default prefix is
/usr/lpp/cbclib/xlc/bin/. If -Bprefix is not specified at all, the prefix of
the standard program names is /usr/lib/cbclib/xlc/bin/.
If -B is specified but -tprograms is not, the default is to construct
path names for all of the standard program names: a, c, L, and l.
Example: To compile myprogram.c so that the name
/u/new/compilers/ is prefixed to the binder and assembler program
names, enter:
xlc myprogram.c -B/u/new/compilers/ -tla
-W Passes the listed options to a designated compiler program where
programs are:
v a (assembler)
v c (z/OS XL C/C++ compiler)
v I (Interprocedural Analysis tool - compile phase)
v l (binder)
xlc and xlC
