Paul,

if by PRJ, you mean ESRI Shapefile .prj files whose WKT definition strips off the 
EPSG code even when the WKT is derived from an EPSG definition, then indeed 
there's some magic to add in GDAL to guess the EPSG code. There's a 
AutoIdentifyEPSG() method ( 
http://www.gdal.org/classOGRSpatialReference.html#acb0373c83927bfd694048da6f79e33ea 
) but it is fairly limited.
