La_svd compiler error

From the sounds of it, it doesn't bode well for me compiling this package for windows then?

Dear All,

I have been trying to compile a package for windows that we have
written. Since R version 3.0.0 the package doesn't compile any more.
(On Linux the package compiles without errors).
The error specifically says:

gcc -m32 -I"C:/PROGRA~1/R/R-30~1.0/include" -DNDEBUG
-I"d:/RCompile/CRANpkg/extralibs64/local/include"     -O3 -Wall

galgo_fitnesses.o:galgo_fitnesses.c:(.text+0xda1): undefined reference
to `La_svd'
collect2: ld returned 1 exit status

specifically from the error I understand that error occurs in the link
to La_svd which is defined in the first couple of lines in the code:

#include <math.h>
#include <R.h>
#include <Rinternals.h>
#include <Rmath.h>

SEXP La_svd(SEXP jobu, SEXP jobv, SEXP x, SEXP s, SEXP u, SEXP v, SEXP
method);

You reported this as a bug, and were told what to do to try to fix it.
Did that work?

Unlikely.  La_svd is not an entry point anywhere in R 3.0.0.
The package may compile on Linux, but that allows unsatisfied entry points.  See 'Writing R Extensions'.

There was a non-API entry point of that name in 2.15.x, but that's not current.
