When gzopen() is called on an empty file, gzgets() reports end of file
properly, but gzerror() returns the Z_BUF_ERROR. I think that the Debian
patch fixing problems with empty files solves the problem only partially
and that it is necessary to set the transparent mode to 1 in this case.
Patch follows:
