Hi Ed,
I don't think this is a bug with Integrate. An indefinite integral
always contains an arbitrary constant, and so Mathematica is free to
choose to add a complex constant.
A possible solution to your problem is to do a definite integration from
a to W, where your function F is zero when its argument is a. For
example, your function F is zero when W is zero, so
Integrate[test, {W,0,W}]
should return a function which is equivalent to F, as long as test has
no singularities on the integration contour. Unfortunately, test does
have a singularity between 0 and 1 for your choice of constants, so the
above doesn't work.
