Hi Thom

I had a similar problem and don't really know the correct way to fix this but ...

I just hand edited my cpl_config.h as attached and things seem to work OK

You will probably want to edit this line to reflect what is in your current file
This is what --prefix=WAS_SET_TO in your configure

/* --prefix directory for GDAL install */
#define GDAL_PREFIX "/usr/mingw"
