re-writing algorithms in Guile

[Tim Meehan]

Say for instance, I have found an algorithm for scalar function
minimization on a website, written in C. It is posted with a license for
use. If I write something based on this hypothetical code, is it then
clearly also licensed in the same manner?

Granted, I know that this is guile-user and not guile-lawyer, but in many
cases the transformation from procedural to functional is kind of a radical
re-imagining. I usually try to contact the people and ask them directly,
but was wondering what was the general consensus in cases where the
original author did not answer?
