R-devel on FreeBSD: new C99 functions don't build
...math/R-devel
It seems, that at least one new C99 function (log1pl) is introduced in
R-devel, see
src/nmath/pnbeta.c:l95
return (double) (log_p ? log1pl(-ans) : (1 - ans));
for which there is only a declaration in FreeBSDs math.h, but no full
implementation in libm (see http://wiki.freebsd.org/MissingMathStuff).
Is there any chance to get at least rudimentary replacement functions in
R-devel for systems with missing or defective C99 math functions?
(For example, in the similar case of log1p(), see the RMATH_HAVE_LOG1P
and RMATH_HAVE_WORKING_LOG1P bits in the configure script,
src/include/Rmath.h0.in...
