[GRASSLIST:3323] no false norting in tmerc projection

[Markus Herrchen]

Hi,
I have a problem in the definition of the coordinate system.
I created a new location and mapset with the following PROJ_INFO file:

name: Transverse Mercator
datum: nad27
dx: -22.000000
dy: 157.000000
dz: 176.000000
proj: tmerc
ellps: clark66
a: 6378206.4000000004
es: 0.0067686580
f: 294.9786982000
lat_0: 42.0000000000
lon_0: -114.0000000000
k_0: 0.9996000000
x_0: 500000.0000000000

But i was unable to define a false northing (in my case of 100000.).
I added by hand a last line with

y_0: 100000.0000000000

but this didn't help. In fact, when i load an ARC/INFO grid file,
by the help of r.in.gdal, the resulting y-coordinate is false:
the false northing is ignored!
Is this a bug in the tmerc projection?

Thanks a lot for the help
Markus Herrchen
