Gary V. Vaughan reported in
that on HP-UX 11.23:

The test-lseek.sh failure was already fixed on 2007-05-30.

The test-vasprintf-posix failure I cannot reproduce with CC="cc -Ae" on
the machine td176.testdrive.hp.com (an ia64-hp-hpux11.23 machine). Can
you investigate what is the result of printf %Lf NaN on your machine?

1) With the native printf, like this:
==================== foo.c ===================
#include <stdio.h>
int main () 
  static long double zero = 0.0L;
  char result[100];
  sprintf (result, "%Lf", zero / zero);
  printf ("%s\n", result);
  return 0;

2) With the gnulib vasprintf, by inserting an fprintf(stderr,...) statement
near test-vasprintf-posix.c:1238 ?
