moving towards the standard ANSI with old c code

[Jim Klavetter]

2 related sets of questions:

1.  What is the timescale for all compilers to be ANSI?  And what is
the timescale for most compilers not accepting old c (I know it is
often called K&R c, but I will use the term old C to mean nonANSI c)?

2.  When should I be worrying about updating my libraries (if not my
programs) to ANSI c?  Should this be done all at once or can I do it
as needed?

It is obvious that it needs to be done sometime, but when?
