[Zsync-users] off_t print macro not working on ARM [patch]

[René F. <re...@fi...>]

Hi,

I've successfully compiled zsync for ARMv7, but downloading didn't work.

After some debugging, I found that the "Range: bytes=" header contains
garbage data.
This is because sizeof(off_t) == 8 and SIZEOF_OFF_T == 4 (defined by
configure). This confuses format_string.h to incorrectly define the 32-bit
version of the OFF_T_PF macro.

The following patch fixes should fix it (tested on ARMv7 and x86-64).

Kind regards,
Rene
