[Rd] Problem with configure's detection of glob on 2.6.0 (PR#10468)

[ripley at stats.ox.ac.uk]

I've no idea about the glob detection, but clearly this is the first 
system that allegedly lacks glob that we have encountered: the file needs 
to be

#if defined(HAVE_GLOB) || defined(Win32)
     glob_t globbuf;
#endif

Have fixed that for 2.6.1 patched.
