Hi,

I'm trying to use indent on an existing C source which contains header files
with preprocessor statements.

As is common in C, the headers are all surrounded by guard statements, so t=
he
final header file looks like this:


```
#ifndef _MY_HEADER_H
#define _MY_HEADER_H

#define FOO bar

#endif
```

Here, the `#define` is not really defined one level deep. Yet, using the `-=
ppi`
option will cause this file to be formatted like this:

```
#ifndef _MY_HEADER_H
#define _MY_HEADER_H

#   define FOO bar

#endif
```

Is there any way to teach GNU Indent about the idea of header guards so as =
to
prevent it from formatting all preprocessor command in a header file with 1
level too deep of indentation?

Thanking You,
