Did you 'make clean' after applying the patch and before rebuilding GDAL ? The
reporter of https://trac.osgeo.org/gdal/ticket/4430 confirmed that the above
patch fixed building for him.

Selon chenliang wang hi181904...@msn.com:

 Thanks for your reply. I have tried 'make clean' and then rebuild GDAL.
 And I have also modified GNUmakefile ,replaed '${GDAL_ROOTs}' for '.'
 and then 'make clean' and rebuild it again. Unfortunately, I failed
 again. I use command ' ./configure --prefix=. ' Should I need to add
 option '--host=mingw32' or '--without-libtool'?

I have not a mingw environment to test. Is it a compilation problem or a linking
problem ?
