arla-block-TR1 compilation problem

[Anders Selander]

I just got yelled at by haba for confessing that I didn't report
my problems the first time I tried to compile arla-block-TR1, so
to repent my wicked ways, I will do it now instead. 

I already have the normal arla working (see
http://www.manja.se/selander/ubuntu_t22/#arla), but think that 
arla-on-blocks will have something to offer when one saves an email 
in an already very huge folder stored in afs. ;-)

You might find configure.out and make.out in 

  /afs/pdc.kth.se/home/s/selander/Public/arla-block-TR1/

interesting.

I have included the outline and the problematic section below.
The "tar: Cowardly refusing to create an empty archive" I can
get rid of by changing Kconfig to kconfig in the nnpfs/linux
Makefile. Why there is no Kconfig but kconfig directories in my 
distribution is beyond me.

However, the three warnings still remains and unfortunately seem
to topple the whole compilation:

  arla-block-TR1/nnpfs/linux/nnpfs/nnpfs_locl.h:163: warning: "struct nnpfs_cache_handle" declared inside parameter list
  arla-block-TR1/nnpfs/linux/nnpfs/nnpfs_locl.h:163: warning: its scope is only this definition or declaration, which is probably not what you want
  arla-block-TR1/nnpfs/linux/nnpfs/nnpfs_dev.h:62: warning: "struct nnpfs_message_wakeup_data" declared inside parameter list

Where are theu supposed to be defined and included? I am especially
intriqued over the nnpfs_message_wakeup_data struct, which a recursive
grep only indicates being defined in ./doc/nnpfs.txt. 

I have tried to compile both with gcc 3.4.5 and 4.0.2 with the same
result.

What crucial information has I failed to convey?
