avoid two warnings:

- recompiled enet without /GL and /LTCG because the game's release mode
doesn't include those, either (due to their heavy compile-time impact)
- wdbg_heap: wrap all allocation-hook logic in #ifndef NDEBUG to avoid
unreferenced local function warnings

This was SVN commit r6201.
