I also find this hard to believe.  C is a very different 
language structure than FORTRAN.
I checked out a Bell Unix distro on the PDP-11 and the 
FORTRAN compiler that came with it.
it had several big errors in implementing the standard 
FORTRAN language, and also printing out floating point 
numbers was laughably slow.  We decided to go with RSX-11M 
instead.  That experience put me off Unix-derived systems 
for years.  it made me think that that version of FORTRAN 
was not likely to have ever been used very much.
