[R] Conflicting headers (was R_qsort_int_I() error)

[Prof Brian Ripley]

Do look at the code: Rmath.h contains

#ifdef MATHLIB_STANDALONE
 typedef enum { FALSE = 0, TRUE } Rboolean;
#else
# include <R_ext/Boolean.h>

/* for API back-compatibility -- DEPRECATED since R 1.2 -- */
#define LTRUE  TRUE
#define LFALSE FALSE
#endif

Is this code to be linked into R?  If so you should not be defining
MATHLIB_STANDALONE: if not, you should not be using R_ext/Utils.h.

PLEASE do, and don't use misleading subject lines.
