This slightly broke error recovery for:

extern int var __attribute__ ((alias ("undef")));

Before:

~/build/gcc/native32/gcc/cc1 -quiet t.c
t.c:1:12: error: 'var' aliased to undefined symbol 'undef'
 extern int var __attribute__ ((alias ("undef")));
            ^

After:

~/build/gcc/native32/gcc/cc1 -quiet t.c
t.c:1:12: error: 'var' aliased to undefined symbol 'undef'
 extern int var __attribute__ ((alias ("undef")));
            ^
t.c:1:12: error: 'var' aliased to undefined symbol 'undef'
