Define this to be a string constant containing @option{-D} options to
define the predefined macros that identify this machine and system.
These macros will be predefined unless the @option{-ansi} option (or a
@option{-std} option for strict ISO C conformance) is specified.
In addition, a parallel set of macros are predefined, whose names are
made by appending @samp{__} at the beginning and at the end. These
@samp{__} macros are permitted by the ISO standard, so they are
predefined regardless of whether @option{-ansi} or a @option{-std} option
is specified.
For example, on the Sun, one can use the following value:
@smallexample
"-Dmc68000 -Dsun -Dunix"
@end smallexample
The result is to define the macros @code{__mc68000__}, @code{__sun__}
and @code{__unix__} unconditionally, and the macros @code{mc68000},
@code{sun} and @code{unix} provided @option{-ansi} is not specified.
