--- Comment #2 from David Summers <beagleboard at davidjohnsummers dot uk> --- I suspect its the newlib includes that trigger the problem. As it I did one compile, where the configure grabbed the host includes (and 64bit system); and that compile I think worked fine. My problem though, as my target is a small 16bit cpu, I need the smallest library, and newlib nano seems to work well - so that will be the library on the machine where the code is run ..,
