+/* 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. */
