[Rd] pcre library in R (PR#9319)

[Prof Brian Ripley]

Please, use the current version of R and not an obselete one (you failed 
to report the version, but you do have 'R-2.4.0' in the path name, so I 
presume that is what you are using).  This does not occur under 2.4.1.

(The problem is in the binutils you are using to cross-compile, and an 
alternative is to update that.)

If you want to fix 2.4.0 and use your cross-compiler, I think you can 
remove pcre_dfa_exec.c and remove mention of it from Makefile.win.
