On my macosx setup (and Henrik confirmed it on a real installation), these 
constants are defined as:

#define TIOCMBIC _IOW('t', 107, int)
#define TIOCMBIS _IOW('t', 108, int)
#define TIOCM_DTR 0002

So that seems to indicate they are int's not long's. My linux manpages also 
confirms int. And the macosx references I could find, tell me the same:

https://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man4/tty.4.html

Strange. Maybe there is some difference between 32bit and 64bit? My apps are 
32bit, and I suspect a native build will be 64bit. Can anyone try to build a 
32bit version on a native macosx?
