Take the following preprocessed souece:
# 1 "t.c"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "t.c"
# 1 "t.h" 1
1
# 2 "t.c" 2
-------- cut ----------
with this in 3.3.3, we got:
In file included from t.c:1:
t.h:1: error: parse error before numeric constant
But in 3.4.0 and above:
t.h:1: error: expected unqualified-id before numeric constant
Which does not help at all.
