Re: [ft] 64-bit compile warning in Visual Studio 2010

From: Ladislav Dudáš
Subject: Re: [ft] 64-bit compile warning in Visual Studio 2010
Date: Sun, 17 Feb 2013 19:31:03 +0100 
Here are all warning from 64-bit compile. I can solve some warning very easy
(for example warnings 63-66). Most of warning depends on FT_ALLOC macros
(and another memory functions and macros). Next use of macros NEEDBITS and
LEAVE needs check, due these macros are dependent on zlib.

So my question is easy: Can I safely ignore these warnings?

- Laco.

Here is the output from 64-bit compilation in VS 2010:
