-__BIG_ENDIAN__ Set this if your platform stores integers and
- floats in big-endian format. Mixed-endian
- systems (different layout for ints and floats)
- are currently not supported.
-NANOPB_INTERNALS Set this to expose the field encoder functions
- that are hidden since nanopb-0.1.3. Starting
- with nanopb-0.2.4, this flag does nothing. Use
- the newer functions that have better interface.
+PB_NO_PACKED_STRUCTS Disable packed structs. Increases RAM usage but
+ is necessary on some platforms that do not
+ support unaligned memory access.
