It would be really cool if Embarcadero broke with tradition of ignoring anything older than one year and included a unified include file that provides all the conditions that numerous third party libraries need to keep supporting multiple compilers, which Embarcadero then updated and included with each new release. We could even write it for them.
Component vendors would need a one-off update to the new format, and to include the initial version for the existing users, but would no longer need to keep updating their own versions.
