All C failures I get with the patch applied are the following:
FAIL: gcc.c-torture/compile/packed-1.c  -O2  (test for excess errors)
FAIL: gcc.dg/torture/builtin-math-4.c  -O0  (test for excess errors)
FAIL: gcc.dg/torture/builtin-math-4.c  -O1  (test for excess errors)

FAIL: gcc.dg/torture/builtin-math-4.c  -O3 -g  (test for excess errors)
FAIL: gcc.dg/torture/builtin-math-4.c  -Os  (test for excess errors)
FAIL: gcc.dg/tree-prof/pr34999.c compilation,  -fprofile-use -D_PROFILE_USE

So hopefully all of those are fixed now. 
I will look into pr30965.C now.

My apologizes for the breakage.  Testing empty patches is obviously easy
job :(
