config.guess contains a heredoc which is used solely on HP-UX to determine
the CPU type and kernel revision being used:

             sed 's/^              //' << EOF >$dummy.c
              #include <stdlib.h>
              #include <unistd.h>

              int main ()
              {
              #if defined(_SC_KERNEL_BITS)
                  long bits = sysconf(_SC_KERNEL_BITS);
              #endif
                  long cpu  = sysconf (_SC_CPU_VERSION);

                  switch (cpu)
                {
                case CPU_PA_RISC1_0: puts ("hppa1.0"); break;
                case CPU_PA_RISC1_1: puts ("hppa1.1"); break;
                case CPU_PA_RISC2_0:
              #if defined(_SC_KERNEL_BITS)
                    switch (bits)
                        {
                        case 64: puts ("hppa2.0w"); break;
                        case 32: puts ("hppa2.0n"); break;
                        default: puts ("hppa2.0"); break;
                        } break;
              #else  /* !defined(_SC_KERNEL_BITS) */
                    puts ("hppa2.0"); break;
              #endif
                default: puts ("hppa1.0"); break;
                }
                  exit (0);
              }
EOF

It does not affect how other test fragments (like, say, AC_C_CONST) are
compiled.
