RTS headers don't compile as C++

GHC's RTS headers can't be included from C++, as they contain constructs like this

dbl_link_replace(bdescr *new, bdescr *old, bdescr **list)

(notice the 'new'). This is the case for the headers shipped with 7.6.3 and still seems to be in the HEAD version.

Since the code has the usual

#ifdef __cplusplus
extern "C" {
#endif

all over the place, I assume the C++ incompatibility is simply an oversight? In any case, it would seem highly unusual to have a C interface that can't be consumed from C++. It seems all the incompatibilities could be removed with at worst a small amount of inconvenience, and automatic checking for C++ compatibility on each build could be added.
