-/* This macro is similar to `TARGET_SWITCHES' but defines names of
- command options that have values. Its definition is an
- initializer with a subgrouping for each command option.
-
- Each subgrouping contains a string constant, that defines the
- fixed part of the option name, and the address of a variable. The
- variable, type `char *', is set to the variable part of the given
- option if the fixed part matches. The actual option name is made
- by appending `-m' to the specified name.
-
- Here is an example which defines `-mshort-data-NUMBER'. If the
- given option is `-mshort-data-512', the variable `m88k_short_data'
- will be set to the string `"512"'.
