libfreenect/fakenect/fakenect.c:78: bad type for local variable ?

libfreenect/fakenect/fakenect.c:78]: (warning) Storing fgetc() return value in char variable and then comparing with EOF.

Source code is

```
char c;
while ((c = fgetc(fp))) {
    if (c == '\n' || c == EOF)
```

Suggest change type of c from char to int. I found this bug in the
latest sources in git with static analyser cppcheck.
