Not all options must be given on the compiler command line. The compiler can use a configuration file which can contain the same options as on the command line. Unless you specify the -n (see page 5.1.1) option, the compiler will look for a configuration file fpc.cfg in the following places:
Versions prior to version 1.0.6 of the compiler used a configuration file ppc386.cfg. This file is still searched, but its usage is considered deprecated. For compatibility, fpc.cfg will be searched first, and if not found, the file ppc386.cfg will be searched and used.
