Subject: read_index(): fix reading extension size on BE 64-bit archs
X-Git-Tag: v1.6.6.1~23^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=07cc8ecac0313c571cb9838585b376df86c80563;p=git.git

read_index(): fix reading extension size on BE 64-bit archs

On big endian platforms with 8-byte unsigned long, the code reads the
size of the index extension section (which is a 4-byte network byte
order integer) incorrectly.
