  We give a Descartes'-like bound on the number of positive solutions to a
system of fewnomials that holds when its exponent vectors are not in convex
position and a sign condition is satisfied. This was discovered while
developing algorithms and software for computing the Gale transform of a
fewnomial system, which is our main goal. This software is a component of a
package we are developing for Khovanskii-Rolle continuation, which is a
numerical algorithm to compute the real solutions to a system of fewnomials.
