You should first look the line 43 in :

/srv/build/obj/alphaev56-dec-osf5.1b/libstdc++-v3/include/tr1_impl/cctype

because the problem is there... My thought (by the sources) is that
somehow the '_GLIBCXX_USE_C99_CTYPE_TR1' (in 
'libstdc++-v3/include/tr1/cctype'), is defined by the configure... What
it means and why could be investigated from the possible 'config.h' in
libstdc++-v3 build directory....
