Is this what
{$linklib c}
does ?

I just copied it from dl.pp in the svn.

I can't believe that the linker should automatically search for 
potentially usable dynamic libraries: in fact it does not know on which 
machine the program is supposed to run.

I installed the "TAR distribution" of fpc and the libraries, so I assume 
a compiled version of cprt0.as came from same.

the svc version of /linux/arm/cprt0.as contains this

....
         .type   _init,%function
         .type   _fini,%function
         .weak   _init
         .weak   _fini
....

So it does not seem to _require_ the symbols to be provided.

Anyway, there is nothing I can do about cprt0 :-( .
