Command-line options

The compiler options controlling the standard include paths are shown in the table below. The value for paths is specified by the user on the command line. When a configuration file is used, the value for paths is the value of the attribute named in the second column. The configuration file used by default is that which was created by the vac_configure utility. The compiler processes each attribute in the configuration file to create the corresponding option that ensures the proper search path for include files.
