I am seeing many erratic errors starting with this revision.  Examples from two
different runs on the same revision:

FAIL: gcc.dg/20040622-2.c (test for excess errors)
FAIL: gcc.dg/cpp/defined.c  (test for errors, line 24)

ERROR: unmatched open brace in list


The errors are like this:

Excess errors:
/home/seurer/gcc/git/gcc-13-test/gcc/testsuite/gcc.dg/cpp/include2.c:10:18:
warning: extra tokens at end of #include directive

Line 10 has a comment after the #include:

#include <silly\>>  /* { dg-error "extra tokens" } */

or maybe it is now mishandling the \>.

Excess errors:
/home/seurer/gcc/git/gcc-13-test/gcc/testsuite/gcc.dg/cpp/include2a.c:10:18:
warning: extra tokens at end of #include directive
/home/seurer/gcc/git/gcc-13-test/gcc/testsuite/gcc.dg/cpp/include2a.c:10:48:
warning: missing terminating " character


The specific ones that fail vary from run to run but that last ERROR one is
always there.

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
No there is a missing `}` in the line that was done for
testsuite/gcc.dg/analyzer/null-deref-pr108251-smp_fetch_ssl_fc_has_early-O2.c :


/* { dg-bogus "may result in an unaligned pointer value" "Fixed in
r14-6517-gb7e4a4c626e" { xfail short_enums } */

There is a missing `}` in that comment.
