[R] package with fortran 90 subroutines under windows xp

[Cinzia Viroli]

Hello,
I work under windows xp and I am trying to build a R package with a 
subroutine written in fortran 90.
I have installed all the updated tools and I am working with R-2.4.0 or 
R-2.5.0.

When I check a package with a subroutine in fortran 77 (and extension f) 
everything is ok.
When I try to build the same package with a subroutine in fortran 90 (with 
extension f90) the following warning appears:

Subdirectory 'src' contains no source files

and the package can not be built.

The funny thing is that I have successfully built the same package with 
fortran 90 last March and everything was good.

I can not imagine what is the problem, could do you help me?
