../../gcc/cppfiles.c:823: size of array `intermed' has non-integer type

[John David Anglin]

Under hpux9.01, PIPE_BUF is only defined in limits.h if _XPG2 is defined.
Here is the warning in the include file:

/*
 * The following limits are not actually invariant, but can vary by file
 * system or device.  the correct values can be determined using the
 * pathconf() function.  The default values are provided here because the
 * constants are specified by several publications including XPG Issue 2
 * and SVID Issue 2.
 */

...

#    define PIPE_BUF    8192    /* max number bytes that is guaranteed
				   to be atomic when writing to a pipe */
