Standards of Fundamental Astronomy - Issue: 2009-02-01 Changes

The leap second of 2008 December 31 was added to the iau_DAT routine, and the "release year" changed to 2009.
Cosmetic changes were made to: bi00.for, bp00.for, bp06.for, dtdb.for, eect00.for, eors.for, epb.for, epb2jd.for, epj.for, epj2jd.for, epv00.for, eqeq94.for, era00.for, fk5hz.for, gmst00.for, gmst06.for, gmst82.for, gst06a.for, hfk5z.for, nut00a.for, nut00b.for, nut06a.for, nut80.for, obl06.for, obl80.for, p06e.for, pfw06.for, plan94.for, pmat76.for, pn00a.for, pn00b.for, pn06.for, pnm06a.for, pr00.for, prec76.for, pv2s.for, pvup.for, rm2v.for, rv2m.for, s00.for, s06.for, sp00.for, starpm.for and xy06.for
Revised license text.
The file board.lis was updated to reflect membership changes.
Revised intro.lis, sofa_vml.lis and sofa_lib.lis, covering the new C version.
Test program t_sofa_f.for added.

An error in the C version of the DAT routine was corrected. The error, not present in the Fortran version, applied only to dates in the first half of 1972. The consequences were platform-dependent; in the test environment the error left the results unaffected, but with other compilers and computers, wrong answers or even arithmetical exceptions were possible.

A bug affecting the routines FK52H and H2FK5 (both Fortran and C) has been corrected. This caused erroneous proper motions (and also radial velocity) to be returned.
The testbeds t_sofa_f.for and t_sofa_c.c have been updated to reflect the changes to FK52H and H2FK5.
In the C header file sofa.h, an unused reference has been removed.
In the C functions iauFk5hip, iauGmst00, iauObl80 and iauObl06, use of the ANSI C language feature "unary plus" has been eliminated, to avoid difficulties with older compilers.

An error in the description of the coordinates of the Celestial Intermediate Pole with respect to the International Terrestrial Reference System in the routines C2T00A, C2T00B, C2T06A, C2TPE, C2TXY and POM00 has been corrected in both the Fortran and C libraries. These revisions have no effect on the results produced by these routines.
