Thank you for all your valuable suggestions!

I've now relicensed the units under the modified LGPL (as used by
Lazarus) and the examples as public domain.

Additionally I've included the above macro (using "extdecl").


I also updated my other Pascal translations for the GNU Readline library
https://github.com/hansiglaser/pas-readline and the TCL interpreter
https://github.com/hansiglaser/pas-tcl . Note that the GNU Readline
library is pure GPL itself, therefore my stuff is GPL too.
