+Use correct mechanism to determine 32/64 bits
+
+Python setup.py builds certain extensions (dl and imageop) only on 32
+bits architecture. However, to test whether the architecture is 32
+bits or not, it was looking at the sys.maxint value of the host Python
+interpreter... which might run on a 64 bits architecture even though
+the target is 32 bits, or which might run on a 32 bits architecture
+even though the target is 64 bits.
+
+Therefore, we introduce a is_arch_64_bits() function, which looks at
+the pyconfig.h file generated by ./configure for the value of
+SIZEOF_LONG to determine if the architecture is 32 or 64 bits.
