You must simply declare it as an external procedure, and call it.
This is explained in the docs.

In a C program you should declare something like

extern void FPC_INITIALIZEUNITS (void);

and then just

main () {

  FPC_INITIALIZEUNITS();

}

in a pascal program, do a

procedure FPC_INITIALIZEUNITS; external;


begin
  FPC_INITIALIZEUNITS;

No that will not help.
