Have gzputc return the character written instead of the argument.
When successful, gzputc would return the second argument. If the
second argument were -1, gzputc would return -1 instead of the
character written, which was 255. However the -1 would not be
distinguishable from an error. Now gzputc returns 255 in that
case.
