La_svd compiler error

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  -std=gnu99 -mtune=core2 -c galgoDistance.c -o galgoDistance.o
gcc -m32 -I"C:/PROGRA~1/R/R-30~1.0/include" -DNDEBUG     -I"d:/RCompile/CRANpkg/extralibs64/local/include"     -O3 -Wall  -std=gnu99 -mtune=core2 -c galgo_fitnesses.c -o galgo_fitnesses.o
gcc -m32 -shared -s -static-libgcc -o galgo.dll tmp.def galgoDistance.o galgo_fitnesses.o -LC:/PROGRA~1/R/R-30~1.0/bin/i386 -lRlapack -LC:/PROGRA~1/R/R-30~1.0/bin/i386 -lRblas -lgfortran -Ld:/RCompile/CRANpkg/extralibs64/local/lib/i386 -Ld:/RCompile/CRANpkg/extralibs64/local/lib -LC:/PROGRA~1/R/R-30~1.0/bin/i386 -lR
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);
