Dear all

I have downloaded the patch file from bugzilla 1320, i am using TortoiseSVN
1.1.1 but i am not able to merge, it says that The line "index:" was not
found.

Might be that diff or patch file is generated by some other software, so
that svn is not recognise it. Please any one suggest me that how can i merge
this patch in version libtiff 3.8.2. Or Is there any other option to get
fully updated ( with all patches) code of libtiff.

Thanks
Anurag Singh
