Borland's habit of altering the binary format of the TPUs for each version
of Turbo Pascal (4.0, 5.0 and 5.5) has been a real nuisance if you have 
purchased binary libraries from other vendors.  The Turbo Analyst Package
had a good solution to this.  Their 5.0 version (after they got burned by
the 4.0 to 5.0 change) had their TPUs in a mangled source form rather than
in binary form.  Thus when 5.5 came along all their customers had to do
was recompile the mangled source to generate the new binary format.  Their
mangled source is not human readable, but will get through the compiler.

Borland would do us all a service if they provided a utilitiy for 
automatically upgrading binary TPUs.  (The only upgrade programs I have
seen from them upgraded 3.0 SOURCE to 4.0 SOURCE - it wouldn't do anything
for binarys).
