SIX-2.1.0
•The configure step now generates header files based on the system which eliminates the need to set the vast majority of defines when integrating the SIX library into other build systems / applications
•Fixed a bug on Unix where if sys/param.h was included before some SIX headers, seg faults would occur (due to an implementation detail in nrt/Types.h)
