The "plain old" bit was only an idiomatic expression (like "good old X", in 
contrast with brand spanking new Python).  It wasn't a reference to K&R or 
any specific standard.  But you are right, C99 does offer some nice 
features, particularly if complex numbers are required.

Who said it was?

Why is that relevant?  There is quite a lot of fundamental libraries which 
are used in this very day that are written with Fortran 77, and don't even 
have a Fortran90 version available.
