So let's find out what causes the difference: if you can send me the 
working signal executable compiled by either GCC or VisualStudio maybe I 
can spot an obvious difference that might matter and produce some example

(I'm not currently setup to run Windows anywhere, so can't really help 
debugging the problem any other way).
