Compared to mode objfpc: no.
Other modes might have other aligns and calling conventions. But you
can change that with compiler directives, so basically a mode is just a
nice set of start switches.

The command line parameters are applied to the whole project, the
compiler directives only to the unit.

See compiler directives.
