Are you saying that ThinkC and Unix will not allow something like:

link my_main with (my_)printf and anything else needed from lib c
(except the copy of printf in there)

where the printf explicitly specified also exists in lib c, but I wish
it to be superceeded by my version?

Then the ThinkC and the Unix linker are outmoded and weak, to say the
least.  REAL linkers have allowed this sort of selective replacement
for years. (Even CP/M allow(s/ed) this).
