FORTRAN charcter strings

Hello, I try to use a Windows DLL with FORTRAN routines in R. All routines work fine, except those which exchange a character variable with R. The documentation "Writing R Extensions" says it's compiler dependent whether character string exchange works with FORTRAN routines or not. Why doesn't it work with every compiler?
Why should it? Why should the designer of a Fortran compiler anticipate that Thomas Dick would want to call subprograms from a C routine and pass in C character strings, and then spend time writing code to meet his wishes?
Does anyone know a FORTRAN90 compiler for windows that works?
No. Not even the matching g77 works. *But* translation by f2c will work. Otherwise write a wrapper in Fortran that avoids having to pass character variables around.
