#22 Segmentation fault on mipsel - wrong type for size variable in window.c

[Markus Koschany]

Hello,

xarchiver segfaults on mipsel. See https://bugs.debian.org/757252 for more information.

The reason is that the type for the size variable in window.c was changed from guint64 to unsigned long int. The size of the latter is not guaranteed to be the same on all different platforms. guint64 is therefor the better solution.

Patch is attached.
