WII: Linking against libntfs.a throws some exceptions

[GoogleCodeExporter]

I'am using DevKitPPC R26 for compiling my code. The Linker throws the following 
exceptions:
->
/opt/devkitpro/3rd/wii/lib/libntfs.a(security.o): In function 
`link_single_group.isra.6':
security.c:(.text.link_single_group.isra.6+0x20): undefined reference to

Did I something wrong or newer DevKitPPC versions don't work anymore?

The Linker throws that exception only if I use the flag:
-Wl,--no-gc-sections

Yeah those uid/gid functions are not available anywhere in the devkit ppc 
packages. They are not used within the libntfs for the wii and therefore by 
default not linked in the application. This is because the garbace collector 
option "gc-sections" is by default enabled. If you turn it off explicitly, like 
in your case, it will try to link all function symbols found anywhere in the 
library which is not possible because these functions are not available.

To fix this problem the uid/gid functions need to be removed from the libntfs 
source code. I was trying to keep the ntfs-3g source code at its most possible 
original state because it is better maintainable that way. Therefore I did not 
remove anything that does not harm in the default build.
