where suboptions are:

config_file Specifies the name of a compiler configuration file.
stanza Specifies the name of the command used to invoke the compiler. This directs the compiler to use the entries under stanza in the config_file to set up the compiler environment.


The default is a configuration file supplied at installation time. Any file names or stanzas that you specify on the command line or within your source file override the defaults specified in the configuration file.

The -B, -t, and -W options override the -F option.


To compile myprogram.c using a configuration file called /usr/tmp/myvac.cfg, enter:

xlc myprogram.c -F/usr/tmp/myvac.cfg:xlc
