Seems to be a backend problem:
dmd -O wcd.d
dmc -6  wcc.c
gcc -O3 -mno-cygwin -o wccm wcc.d

On my 7.5MB iTunes XML file:
$ time ./wcd < it.xml
303412

real    0m1.078s
user    0m0.015s
sys     0m0.015s

$ time ./wcc < it.xml
303412

real    0m1.063s
user    0m0.031s
sys     0m0.000s

$ time ./wccm < it.xml
303412

real    0m0.172s
user    0m0.015s
sys     0m0.015s

Even if the usage of opt-switches is argueable (sp??) here, 
it is rather a backe-end than language thing.
