sysUtils shipped with the FPC’s default run-time library provides many system utilities.

sysUtils unit is included, all run-time errors become exceptions, which virtually forces you to use a compiler mode (or mode switch) that allows exception treatment.
To catch an exception by its name you will need to include
sysUtils, even though the unit itself does not use any of the included system utilities.
If size matters, using
sysUtils is by design not the smartest choice.
