That was indeed my thought as well. ;-)

In any case, _if_ doing it, I would do it by adding -Fu and -Fi pointing
to the upper (i.e. compiler) directory to the Makefile rule for building
the fpc executable, adding a possibility to pass the version information
from fpc to the respective compiler by adding something like '-V?' +
full_version_string to PPCCommandLine _if_ -V parameter has not been
passed to the fpc executable already (it wouldn't make much sense
otherwise), adding a new warning message to msg/errore.msg and adding
handling of the new parameter to options.pas in the compiler directory.
Obviously, it would only work for compiler versions having this
functionality included, i.e. you couldn't safeguard against having really
old versions invoked that way.

Yes, that should do that.
