binaries: netfilter headers differ only in case

[Michael Hope]

The netfilter headers in usr/include/linux/netfilter{,_ipv6} include files that differ only in case. This is a problem on case-insensitive filesystems such as NTFS.

michaelh@crucis:~/linaro/binary/linaro/builds/test/install$ find . -iname xt_dsc*
./arm-linux-gnueabi/libc/usr/include/linux/netfilter/xt_DSCP.h
./arm-linux-gnueabi/libc/usr/include/linux/netfilter/xt_dscp.h

From Bernard:

"""The following file names appear to differ only by case, which presents a problem when extracting to case-insensitive filesystems: ipt_ecn.h, ipt_ttl.h, xt_mark.h, xt_TCPMSS.h, xt_rateest.h, xt_dscp.h, xt_CONMARK.h, ip6t_hl.h"""

Appears to have been fixed by addition of '_' to ends of uppercase filenames. I guess that the fix has to take this form, but unless these headers are used in some special way, such as only for kernel builds, there's still a problem for Windows users.

Can you confirm that either Windows users just don't ever need to use these headers, or otherwise that the altered names of these headers will be documented somewhere reasonably prominent?

Thanks

I can confirm that neither Linux user space programs, the Linux kernel, or EGLIBC need the linux/netfilter header files to compile.

If we decide to document the differences between the Windows and Linux builds then this will go into it.
