Replying to rouault:
Frank, Didier,
I'm a bit lost and worried by this ticket that replaces Gauss Laborde Reunion that was introduced during 1.6.0 developement (see #2134, r13482 and in r13487) by Gauss Schreiber.
You're right #2134 was the first place I put these changes. Few days ago, I commited them to the trunk (just before the 1.6.0beta1) along with other changes. My commit was reverted by Frank because of too many impacts on the trunk. Frank suggested me to propose tickets for Gauss Schreiber and GTiff (See #2664) between beta1 and beta2 and decide whether or not take them into account (specially for GTiff). That's what I did.
I'm elevating the severity to blocker as we presumably cannot remove projections added in 1.6.0 in later versions. So we must decide *NOW* if we apply those patches, or otherwise we'll have to keep Gauss Laborde Reunion later.
It would be better to switch Gauss Laborde to Gauss Schreiber before the finalisation of 1.6.0.

ok, I finally understood what happened by looking closely at the history of proj4 (really nice that it is under trac now to follow history of changes) : glabsgm was first introduced and then replaced by gstmerc (by the way, the NEWS in proj 4.6.1 is a bit confusing as it gives the impression that glabsgm is also supported)
I've commited the series of patches in r15742, with a slight modification (removing '+dfFromGreenwich' in ogr_srs_proj4.cpp as it was removed a few months ago for all projections in r12535), and addition of the validation of gstmerc in ogr_srs_validate.cpp
