Thanks for the bug report. Now fixed.  I also made all the definitions
double-precision, to avoid the possibility of integer division (some
of the constants are integers).

physic constants (0.9.3)

	Hello!

	btu and barn constants, from the gsl_const_mks, are defined as 'btu' and
'barn' and not the value it should be.

I accept patches ;-)

Extra values can be added to the gsl-constants list in const/const.el

I'd like to see the solar mass (about 2e30 kg) go into the table of constants.
It has AU and pc, but the one big thing missing is solar mass.
