Hi
I've a problem like your one.
I tried to compile a PLUGIN for GDAL and I included files as following:

#include gdal_priv.h
#include hdf5.h
#include gdal_pam.h
#include gdal_priv.h
#include cpl_string.h
#include ogr_spatialref.h
#include cpl_list.h

I had two conflicts between mingw and gdal for variables *_copysign*
and *ssize_t*, defined in both mingw and gdal. 
Should I define some macros or other else when I want to compile GDAL 
with MinGW?

Someone could help us??
