[gdal-dev] compile error on windows

[twhall]

I had previously built HDF5 v1.8.17 as a 64-bit DLL on Windows 10, Visual
Studio 2010.

Today I tried to rebuild GDAL v2.0.2 to include the HDF5 format, but failed
with the undefined symbols as reported by Ryan Grout on Apr. 29.

I followed his advice from May 02, to edit frmts/hdf5/makefile.vc, replacing
-D_HDF5USEDLL_ with -DH5_BUILT_AS_DYNAMIC_LIB, and that fixed the immediate
problem.  GDAL built successfully, though it remains to be seen whether the
HDF5 part actually works.

The dependence on -DH5_BUILT_AS_DYNAMIC_LIB originates in the HDF5 header
H5api_adpt.h:
#ifdef H5_BUILT_AS_DYNAMIC_LIB
   ...
   #define H5_DLL __declspec(dllimport)

Without that, the symbols won't import from the DLL.

I don't see any dependence on _HDF5USEDLL_
