* po/header.pot: Replace with exact boilerplate pinard dictates.
* sysdeps/i386/strtok.S (Lillegal_argument): Remove this code to set
errno and the check that jumped to it.

and long-c-routines. Only if the `long double' data type is
available we need to compile the functions.
(libm-routines): Add $(long-m-routines).
(routines): Remove isinfl, isnanl. Use new file s_isinfl and
s_isnanl instead if `long double' is available.

functions.
* math/math_private.h: Define data types, prototypes and access
macros for `long double'.

frame but stored the values outside.
