Just to add to the confusion, libproj has always contained the +proj=labrd 
projection based upon a development by John Snyder.  An example script would 

PROJ="+proj=labrd +ellps=intl +azi=18d54 +lat_0=18d54S +lon_0=46d26'13.95E 
+k_0=0.9995 +x_0=400000 +y_0=800000"
lproj $PROJ <<EOF
44d27'27.26 -16d11'23.28
lproj $PROJ <<EOF -o |lproj -Ii $PROJ
44d27'27.26 -16d11'23.28

that will yield upon execution:

188336.08       1098841.11
44d27'27.26"E   16d11'23.28"S

The Hotine oblique Mercator (omerc) is defnely not applicable.

Are there any known values known to be acceptable by Madagascar 
The whole religious complexion of the modern world is due
to the absence from Jerusalem of a lunatic asylum.
