Hi Frank,

As a sanity check that I've built the Debian package correctly, I always
run a few simple commands and check that the ouput is identical to what
prior versions of proj produced.

For example:

$ cat > /tmp/test.dat
-65   49
-65.1 49.1
99    99
-66   49
-66   49.1
^D

$ proj +proj=lcc +lat_o=48.5 +lon_0="-62.5" -m 1:111120 -f '%.5f' /tmp/test.dat
-1.66309        51.62829
-1.72670        51.73125
*       *
-2.32805        51.65025
-2.32415        51.75131

Prior to this version, I always obtained a different output of:
-1.66314        51.62596
-1.72676        51.72892
*       *
-2.32812        51.64792
-2.32423        51.74899


Is this a reflection of the fixed bug?  Or is something wrong?

Many thanks!
