-/* NOTE: Because of the special way this file is used by <math.h>, this
- file must NOT be protected from multiple inclusion as header files
- usually are.
-
- This file provides prototype declarations for the math functions.
- Most functions are declared using the macro:
-
- __MATHCALL (NAME,[_r], (ARGS...));
-
- This means there is a function `NAME' returning `double' and a function
- `NAMEf' returning `float'. Each place `_Mdouble_' appears in the
- prototype, that is actually `double' in the prototype for `NAME' and
- `float' in the prototype for `NAMEf'. Reentrant variant functions are
- called `NAME_r' and `NAMEf_r'.
-
- Functions returning other types like `int' are declared using the macro:
-
- __MATHDECL (TYPE, NAME,[_r], (ARGS...));
-
- This is just like __MATHCALL but for a function returning `TYPE'
- instead of `_Mdouble_'. In all of these cases, there is still
- both a `NAME' and a `NAMEf' that takes `float' arguments.
-
- Note that there must be no whitespace before the argument passed for
- NAME, to make token pasting work with -traditional. */
