Details:

The declaration of the gnutls memory function casuses problems.

It is all the memory function but I will try and describe the problem with
gnutls_free.

gnutls_free is declared as follows:
typedef void (*gnutls_free_function) (void *);
extern gnutls_free_function gnutls_free;

when cross-compiled and made to a windows .lib file _fnutls_free is not found
in the library because the declaration misses a __declspec(dllimport).

typedef void (*gnutls_free_function) (void *);
extern __declspec(dllimport) gnutls_free_function gnutls_free;

this is one solution but since the headers is platform independant right now,
a better solution could be to convert the gnutls_free to a real function and
have a placeholder for the gnutls_free_function_pointer that it could call.
void gnutls_free(void *p)
{
   (*gnutls_free_function_pointer)(p);
}

all the function calls in the gnutls library is ok since for functions the
__declspec(dllimport) is implicit.
