2 Command-Line Options
You can specify command-line options to the aCC command. They allow you to override
the default actions of the compiler. Each option begins with either a - or a + sign. Any
number of options can be interspersed anywhere in the aCC command and they are
typically separated by blanks. Unless specified otherwise, all options are supported by
C and C++ compilers.
Default options can be set using option configuration files. See “Configuration Files (.conf
Files)” (page 29).
