Frank,
I intended for thread_safe_signals to be unpacked in a separate directory from your full boost installation. You could then choose to use it (or not) by including the path to thread_safe_signals in your include path, before the path to the full boost installation.
Good call - I switched to doing that. I can detect which version is being used by looking at what got #defined.
Thanks for the bug report, I don't have any Microsoft compilers. Would you try the attached patch?
Worked. Thanks! After building with the latest version, I got some warnings (and an error that only appeared after some time, not sure what triggered it). Patches for the warning and error included, although I'm not sure I handled the error fix the best way. I am still a little bit patch challenged, so if I made / sent the patches wrong somehow please let me know!
