Bug ID: 67087
Summary: FAIL: gcc.dg/cpp/_Pragma3.c (test for excess errors) -
file timestamp issue
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: miyuki at gcc dot gnu.org
Target Milestone: ---
I see the following in test log:

This may be a subversion-specific issue. I have several other GCC trees, but
they all use git and don't have this problem, because the timestamps almost
match:
$ ls --full-time _Pragma3.c mi1c.h
-rw-r--r-- 1 jenkins jenkins 214 2015-06-19 18:40:34.659650568 +0300 mi1c.h
-rw-r--r-- 1 jenkins jenkins 309 2015-06-19 18:40:34.655650549 +0300 _Pragma3.c
Nevertheless I suppose that this test should not depend on file timestamp. The
test is related to timestamp, but AFAIU, it is enough to check that we do not
ICE, and warnings are irrelevant. In that case

is enough (the test passes).
If for some reason silencing all warnings is not appropriate here, the fix will
probably require some kind of file timestamp adjustment. Unfortunately my
knowledge of TCL and various exotic GCC hosts (like Solaris and AIX) is not
good enough to implement it.
