I'm wondering if updating the constants without a possibility to
revert to an earlier version is a good idea.

Would it be useful to have something like

GSL_CONST_MKSA_SPEED_OF_LIGHT_2000
GSL_CONST_MKSA_SPEED_OF_LIGHT_2006

and


GSL_CONST_MKSA_SPEED_OF_LIGHT

to be either of the two, depending on a #define?
