Invalid Pragmas

If you enable the compiler's setting for reporting invalid pragmas, the compiler issues a warning when it encounters a pragma it does not recognize. For example, the pragma statements in The following listing generate warnings with the invalid pragmas setting enabled.

Listing: Invalid Pragmas

#pragma silly_data off       // WARNING: silly_data is not a pragma.

#pragma ANSI_strict select  // WARNING: select is not defined

#pragma ANSI_strict on      // OK

The following table shows how to control the recognition of invalid pragmas.
