Description
US Stateplane projection files are not well recognized due to naming (e.g. FIPS code in ESRI wkt) and/or rounding misalignments between GDAL data and the EPSG Registry.
An example of such prj file is:
PROJCS["NAD_1983_StatePlane_Texas_Central_FIPS_4203_Feet",GEOGCS["GCS_North_American_1983",DATUM["D_North_American_1983",SPHEROID["GRS_1980",6378137.0,298.257222101]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Lambert_Conformal_Conic"],PARAMETER["False_Easting",2296583.333333333],PARAMETER["False_Northing",9842500.0],PARAMETER["Central_Meridian",-100.3333333333333],PARAMETER["Standard_Parallel_1",30.11666666666667],PARAMETER["Standard_Parallel_2",31.88333333333333],PARAMETER["Latitude_Of_Origin",29.66666666666667],UNIT["Foot_US",0.3048006096012192]](Source: http://osgeo-org.1560.x6.nabble.com/gdal-dev-Achieving-Better-WKT-gt-EPSG-Code-Autodetection-When-Importing-Layers-to-Postgis-td5335537.html)
I attach a patch which solves the issue.

Hi Joaquín,
I attach an additional patch that contains further improvements and corrections, because I've discovered that the MorphToESRI() method sometimes makes not possible to export the sr to Proj4. It provides a more robust approximation.
Sorry for the annoyance.
