Hello -- unfortunately we had to remove the electromagnetic constants
from cgs.h because the units weren't defined unambiguously.  It should
be in the Changelog and NEWS, though, with the following messages:

2009-08-17  Brian Gough  <address@hidden>

        * const.el: removed electromagnetic constants from cgs, now only
        in CGSM

** The header file gsl_const_cgs.h no longer defines values for
   electromagnetic units.  Applications should use gsl_const_cgsm.h
   instead to obtain the values in the CGS-Magnetic system.  The
   previous values for these units given in gsl_const_cgs.h were
   incorrect as the type of CGS electromagnetic system was undefined.
   The affected constants are GSL_CONST_CGS_BOHR_MAGNETON,
   GSL_CONST_CGS_ELECTRON_CHARGE,
   GSL_CONST_CGS_ELECTRON_MAGNETIC_MOMENT, GSL_CONST_CGS_FARADAY,
   GSL_CONST_CGS_GAUSS, GSL_CONST_CGS_NUCLEAR_MAGNETON,
   GSL_CONST_CGS_PROTON_MAGNETIC_MOMENT, and GSL_CONST_CGS_ROENTGEN.
