[Proj] NAD_1983_To_WGS_1984_5

Hello,

you have defined datum twice in the "from"  system!

You have 1) datum=NAD83 and also 2) +towgs84=....

You should remove one of them! 

The program says:
    #--- following specified but NOT used
     # +ellps=GRS80 +towgs84=0,0,0

Meaning that it is using datum 1) datum=NAD83 and
using "datum=NAD83" defines "ellps" and "towgs=" already.

Regards: Janne.
