Details:

In src/hwspi.h and src/hwspi.cpp the variable named SS causes an error due to
SS being already defined as "SS [-Wcpp]":

    gmake[3]: Entering directory
`/export/scratch/builds/ada/native/simulavr-1.0.0-obj/src'
    /bin/sh ../libtool --tag=CXX   --mode=compile g++ -DHAVE_CONFIG_H -I.
-I../../simulavr-1.0.0/src    -I/scratch/builds/ada/run/include -g -O2 -Icmd

    In file included from ../../simulavr-1.0.0/src/at4433.h:35:0,
                     from ../../simulavr-1.0.0/src/at4433.cpp:26:
    ../../simulavr-1.0.0/src/hwspi.h:57:19: error: expected unqualified-id
before numeric constant
    gmake[3]: *** [at4433.lo] Error 1

When I insert the statement "#warning Symbol SS" right before line 57 of
hwspi.h I get:

    In file included from ../../simulavr-1.0.0/src/at4433.h:35:0,
                     from ../../simulavr-1.0.0/src/at4433.cpp:26:
    ../../simulavr-1.0.0/src/hwspi.h:57:2: warning: #warning Symbol SS
[-Wcpp]
    ../../simulavr-1.0.0/src/hwspi.h:58:19: error: expected unqualified-id
before numeric constant

This is using gcc 4.7.2 with Ada enabled.

Renaming the variable eliminates the problem.
