Depends on which source you are talking about.  Many things
don't transfer.  Borland libraries (the infamous T series)
are examples.  Much of what doesn't come across is due to
upgrading to ANSI and not keeping the pseudo-Borland
standards. However, much is just dropped.

If you wrote to ANSI standards, then you were probably OK -
there are exceptions. If you used Borland specific
libraries, you have a bit of recoding to do.
