Re: R17.0-rc1 patch for gzio.c compile breakage.

Thank you for the merge.  And you piqued my curiosity as to the why.

My gentoo zconf.h defines the macro as _Z_OF instead of OF.  Digging
deeper, they made the change on the premise that OF is a stupid, polluting
name for an internal macro.  There was disagreement as to the value of the
change (https://bugs.gentoo.org/show_bug.cgi?id=383179)
