DMD doesn't really require GCC, GCC is in theory used for 
compatibility with modules compiled with gcc according to dmd(1), 
and in practice used for linking.

The linking step could be done with ld alone if you know what to 
type, and it's honestly pretty complicated, and you still need 
components from gcc, for various reasons:

LIBGCCDIR=$(cc -print-file-name=)
CRTDIR=/usr/lib/$(cc -dumpmachine)

ld -L $LIBGCCDIR $CRTDIR/Scrt1.o $CRTDIR/crti.o 
$LIBGCCDIR/crtbeginS.o \
YOUROBJECT.o -E --push-state -static -lphobos2 --pop-state \
-lpthread -lm -lrt -ldl -lc -lgcc -lgcc_s $LIBGCCDIR/crtendS.o 
$CRTDIR/crtn.o
