If there is a one-to-one mapping of arguments between the new and old
functions, and the macros merely rearrange the order (and change the
names) then type safety shouldn't be a problem.

How? These apps would need to be recompiled anyway - that way they would
pick up the macros.

Aren't these what you are trying to avoid in the first place? 
The libdes shipped with MIT krbIV is an ongoing source of frustration for
the portable OpenSSH developers.
