line numbers

test case bug.c
Warnings about semantics or code generation should not be inhibited by
preprocessor line statements. But that is what happens for -Wmismatched-dealloc
warnings.
How to reproduce:
1)
$ gcc -Wall -Wmismatched-dealloc -O2 -S bug.c
Actual output: warnings about line 22, 36, 42.
Expected output: warnings about line 22, 31, 36, 42.
2)
$ gcc -O2 -E bug.c | sed -e '/^#/d' > bug1.c
$ gcc -Wall -Wmismatched-dealloc -O2 -S bug1.c
Actual output: warnings about line 22, 29, 36, 42.
