Does any fortran compiler perform a C hidden translation before making obj code?

I wonder if

any fortran compiler performs a C hidden translation before making obj code.

Is it true?

In old/new fortran compiler?

Neither Intel Visual Fortran nor Compaq Visual Fortran do this.

There are myths about this. Many Fortran compilers, including Intel Visual Fortran, share some back end components and an Intermediate Language representation with a C compiler. Even with the few Fortran compilers which do generate C code, it is nearly as unreadable and non-portable as this Intermediate Language.
If you consider f2c to be a Fortran (77) compiler, that is available at netlib.org, and even had maintenance fixes up to a year ago. The C code which it generates (C89 or K&R, or a bit of early C++) is still not intended to be useful as anything but an intermediate file. f2c linkage conventions are like ifort -Qlowercase -us, but the run time library calls are not compatible with Visual Fortran.
