BTW, I don't understand why that fixes it for you either. As you can
see, gzwrite *is* declared with const. The reason why you're getting a
warning is that zconf.h #define's const as nothing unless it thinks
you're on an ANSI compiler (and the difference between 1.1.4 and 1.2.3
is mostly that the former's test for ANSI-ness is brain dead). But if
you're compiling that #define then const or lack of it should mean
nothing to you.
