Preprocessor Features

The compiler provides standard preprocessor functionality, as
cc219x
described in any C text. The following extensions to standard C are also
supported:
// end of line (C++-style) comments
#warning directive
For more information about these extensions, refer to

Predefined Preprocessor Macros
The compiler defines a number of macros to produce information
cc219x
about the compiler, source file, and options specified. These macros can
be tested, using the
gram's needs. Similar tailoring is done in the system header files.
Macros such as
"#" operator with a macro body is useful in converting such symbols into
text constructs.
Table 1-12 describes the predefined preprocessor macros.
