Gnulib causes error prone warnings.

[Mats Erik Andersson]

Hello there,

in order to build 1.0.3 with active "--enable-gcc-warnings",
with Debian Squeeze, I find myself forced to apply the
patching reproduced below.

On one hand, "-Wenum-compare" produces a large number of
comments, since it is ignored while encountered by CC,
and whil being applicable only to C++ and allies.

More severe is the fact that upstream Gnulib is by policy
not acting against compiler warnings inherent in their
code basis.  This hits Shishi in two files:

    gl/timespec.h
    gl/xalloc.h

where four inline functions are missing their prototypes,
warnings which are upgraded to errors when building
with "--enable-gcc-warnings".

Is there a method to relax the use of "-W*" in "gl/"?
The problem is that both the files named above are
referenced in "lib/*", so preprocessor options are
seemingly interdependent. It is unfortunate to mend
files imported from Gnulib, but that was the only
action I could think of.

Regards,
  Mats Erik Andersson
