OK, but is that a bug? C89 says that static variables must be
initialized to zero. These days GNU software tends to assume C89 or
better (it's too soon to assume C99).
Anyway, I installed this patch:
2007-02-11 Paul Eggert <[EMAIL PROTECTED]>
* gzip.c (foreground): Initialize to zero. This doesn't fix a bug
since C guarantees it's zero, but it's more consistent with the
rest of the code. Problem reported by Mark Adler.
