Yes, multiple vendors still have <foo>f90 (and/or <foo>f77)-named compilers.  
But these are just multiple entry points to a common back end, usually for 
legacy reasons (just like we'll still have mpif90 and mpif77).

Another fun fact: MPI-1 was never compliant with Fortran 77.  The most 
obvious/easiest point to cite is that F77 only allowed 6-character variable and 
subroutine names.  :-)
