I'd suggest going for the latest trunk instead of stable. I also have some 
patches on the review board cleaning up the compiler flags.

The "-Wno-unused-value" is added to the SWIG flags in the later editions of the 
Sconscript.

Hello,

I'm new with gem5. I've downloaded the code of the branch gem5-stable and tried 
to compile using scons. Here's the error I get:

 [     CXX] ALPHA/python/swig/core_wrap.cc -> .do
build/ALPHA/python/swig/core_
wrap.cc: In function 'void SWIG_InitializeModule(void*)':
build/ALPHA/python/swig/core_wrap.cc:4233:21: error: statement has no effect 
[-Werror=unused-value]
cc1plus: all warnings being treated as errors
scons: *** [build/ALPHA/python/swig/core_wrap.do] Error 1
scons: building terminated because of errors.

The line is : (void*)clientdata;


Cheers,

Maxime.
