-     dnl The include of <stdio.h> is because IBM C 9.0, 10.1 (original

-     dnl when used as first preprocessor directive in a file, but not when

-     dnl included by specifying its absolute file name. Despite these two bugs,
-     dnl include_next is used in the compiler's <math.h>. By virtue of the
-     dnl second bug, we need to use include_next as well in this case.
