I'm trying to do statement coverage of C sources using gcc -a and tcov(1). This
works fine with then SUN acc-compiler, but programs compiled by gcc persistently
claim they can't find the corresponding .d-file -- Which is hardly surprising, 
considering it ain't there.

What i'd like to know is: Is this a known gcc problem (and if so, is there a fix ?),
have i bungled the installation of gcc, or is there some other magic required to make
this work ?
