My apologies - I sent this to Daniel directly rather than to the list.

I can't get in to to see the relevant bug reports, but I
have similar issues with writing HDF library bindings.  I've ended up
using the following preprocessor lines in my C code to get around this
(the OCaml headers are included above the pasted code):

#define int32 hdf_int32
#define uint32 hdf_uint32
#define int8 hdf_int8
#define uint8 hdf_uint8
#define int16 hdf_int16
#define uint16 hdf_uint16

#include <hdf.h>

#undef int32
#undef uint32
#undef int8
#undef uint8
#undef int16
#undef uint16

I then have to use hdf_int32 and so on in the body of the code
occasionally to silence compiler warnings.

I don't know that this is the best way, but in my case it has allowed
me to do what I need to until a better solution comes along.
