I've managed to work around the breakage by making relatively minor changes 
in the vboxdrv source.

1) include/linux/types.h:40: error: redefinition of typedef ‘uintptr_t’
This error was fixed by commenting out the following code fragment in
include/iprt/stdint.h:

#ifndef _MSC_VER
#ifndef _INTPTR_T_DECLARED
typedef __intptr_t              intptr_t;
typedef __uintptr_t             uintptr_t;
#define _INTPTR_T_DECLARED
#endif
#endif /* !_MSC_VER */

2) include/linux/bitops.h:6:1: warning: "BIT" redefined
The upstream kernel now defines BIT itself (BITOP was renamed to BIT).
I therefore renamed BIT in the vboxdrv source to VB_BIT using:
$ find -type f -exec sed -i "s/\([^_]\)BIT(/\1VB_BIT(/g" {} +

After that the module builds and seems to work fine.
