[Scons-users] CPPDEFINES Unexpected Behavior

but I followed the wrong track. It's not _concat_ixes (that's the one 
for prefix/suffix, which you are not interested in), but 
processDefines(). Here the key/value pairs of the dict get wrapped with 
str() in the same manner, so it would still be interesting to know whether
