[photran] using module while source files are in a folder

["M.R.Hadian" <m.r.hadian@xxxxxxxxx>]

Hi
i want to have source files in a folder to avoid mixing source,
objects, data files. when i use a module in my code, photran can not
build the project.
a sample project including 3 files are attached. 
1.
photran nagging that can not create the .mod file. but when i rename
"VarDef" to "vardef" in all files, the problem removes. Fortran in not
case-sensetive, so it seems that there is a problem.
2. after doing the above task, i got the following error message:
make all 
m2c    -o vardef.o vardef.mod
"vardef.mod": 1: syntax error in compilation unit begin
"vardef.mod": 1: fatal error - file must be named as created.mod

vardef.mod - 0 lines, 160 bytes
make: *** [vardef.o] Error 1

reagards,
Hadian

P.S. i use photran on ubuntu 8.10 and updated the whole eclipse (3.4.2) and its plugins.
program test
    use vardef
    implicit none
    integer :: i
    Print *, "input array dimension:"
    read *,n
    call SetArray
    a=(/(2*i,i=1,n)/)
    print * ,a
end program

subroutine SetArray
    use vardef
    implicit none
    allocate(a(n))
end subroutine SetArray

module vardef
implicit none
    integer,allocatable,dimension(:)::a
    integer::n
end module vardef
