According to Joao Miguel:

It does, just like Borland Pascal.

Like with Borland Pascal, you must either first "compile" all Units, and
then the main program,

  gpc -c myfirstunit.pas
  gpc -c mysecondunit.pas
  gpc myprogram.pas myfirstunit.o mysecondunit.o -o myprogram

or else you "make" the program, i.e. you tell the compiler to compile
all Units automatically.  With GPC, this is done with the `--automake'
option.  The following

  gpc --automake myprogram.pas -o myprogram

automatically compiles `myfirstunit' and `mysecondunit' and links them
to the main program.

(* Just for completeness:  The `-o myprogram' means: output an executable
`myprogram' (or `myprogram.exe') rather than `a.out' (or `a.exe'). *)

Hope this helps,
