ogr2ogr works on Linux, does not on Windows

[Xin]

Keeping you guys up to date, this problem has now been solved.

We created a VRT file for the shapefile.  Convert VRT to TAB with the
following command:

ogr2ogr -f "MapInfo File" address.tab address.vrt -s_srs
"+proj=longlat+ellps=WGS84 +datum=WGS84 +no_defs" -s_srs "+proj=longlat
+ellps=WGS84 +datum=WGS84 +no_defs"

Notice duplicate -s_srs's.  This is needed.  Not sure why, but doesn't work
without it.

Cheers,
Xin
