[Gptfdisk-general] gdisk in gcc 4.6

[KESHAV P.R. <sko...@gm...>]

Hi,
     There seems to be small warnings with gptfdisk compilation (from
git - 0.7.1 tag) with gcc 4.6 in Archlinux x86_64. Below is the output

I will try compiling the same in mingw-w64 gcc 4.6 for Windows 7 x64
and come back to you. Thanks in advance.
