From 2702a61b0e22ddcbd0b23c1765fac90fe766802a Mon Sep 17 00:00:00 2001
From: Lukas Fleischer <calcurse@cryptocrack.de>

Subject: Fix hash table issues with ISO C99

ISO C99 forbids unnamed structs/unions and nested functions. Move the
"HTABLE_HEAD" and "HTABLE_GENERATE" parts out of the function body and
place them at the very top of the file (where function definitions are
allowed). Also, remove the unnamed struct from "htable.h" (which was
useless anyway).
