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.

../../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.
