Mattias, it looks very promising, but will it affect the logic of "build
all" command, currently from what I see from output it doesn't care about
other packages units as long as their dates were not changed. In other
words, what is the menu item I should use to "force" fpc compile not only
units with changed dates, but all units from all packages using and with my
new  $(MyOptions)?
