[Bug testsuite/28123] New: gcc.dg/cpp/_Pragma3.c is sensitive to timestamps

["amylaar at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I got a failure on the cc.dg/cpp/_Pragma3.c test:

Executing on host: /mnt/scratch/nightly/2006-06-20/sh-elf/gcc/xgcc

FAIL: gcc.dg/cpp/_Pragma3.c (test for excess errors)
Excess errors:
/mnt/scratch/nightly/2006-06-20/srcw/gcc/testsuite/gcc.dg/cpp/_Pragma3.c:11:
warning: current file is older than mi1c.h

The timestamps of the two files in question are one second apart:
bash-2.05b$ ls -l --full-time _Pragma3.c mi1c.h
-rw-r--r--    1 renneckej users         214 2006-06-20 14:36:46.000000000 +0100
mi1c.h
-rw-r--r--    1 renneckej users         309 2006-06-20 14:36:45.000000000 +0100
_Pragma3.c

It would appear that this tests success requires that either _Pragma3.c is
checked out after mi1c.h, or both are checked out simultanously as far as the
file system is concerned.
