Makefile question

[Angus Leeming]

I'm damned if I can see what's wrong with this Makefile. Running make gives:
aleem@thorax:xforms$ make
make: *** No rule to make target `form_client.C', needed by `all'.  Stop.

Could someone put me out if my misery please!

Makefile:
FDSRCS = form_client.fd

FDC = $(FDSRCS:.fd=.C)

all: ${FDC}

.fd.C:
        sh fdfix.sh $<

.SUFFIXES = .fd .C
