Luis,

Is it possible you didn't do a "make clean" after reconfiguring with
bigtiff support?  I see the following logic in gdal/frmts/gtiff/geotiff.cpp:


     if( nCompression == COMPRESSION_NONE )
     {
         if( nXSize * ((double)nYSize) * nBands * (GDALGetDataTypeSize(eType)/8)
             > 4200000000.0 )
         {
#ifndef BIGTIFF_SUPPORT
             CPLError( CE_Failure, CPLE_AppDefined,
                       "A %d pixels x %d lines x %d bands %s image would be 
larger than 4GB\n"
                       "but this is the largest size a TIFF can be.  Creation 
failed.",
                       nXSize, nYSize, nBands, GDALGetDataTypeName(eType) );
             return NULL;
#else
             bCreateBigTIFF = TRUE;
#endif
         }
     }

So this error should not be reported if you build with BigTIFF support.
But if you just reconfigure and relink without a "make clean", then
geotiff.cpp won't get rebuilt and you would see the issue you have
run into.
