R devel - Apr 2013 - 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 -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);


Any ideas?
Thanks
Phil

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