And that is indeed what I did. FFLAGS() and OFLAGS() become more complex than just adding and subtracting 1, but that's not difficult to deal with. (If anyone's curious exactly what I did, look at the three commits ending with 5215f8f6551df407d7c87c8e6a80c7b04e9ee844 in the git repo git://git.rodents-montreal.org/Mouse/netbsd-fork/4.0.1/src.) > The fact that the O_ flags were not intelligently specified aeons ago > so that a conversion is required is regrettable, but at this point > unfixable. Actually, I disagree. It is totally fixable. Well, it's unfixable in the sense that we can't change the past choice. But it is fixable in that we do not have to be remain crippled by that choice. Quite aside from someone just having the courage to bite the bullet and write off compatability with such ancient code (are there any known extant examples?), it's possible to do something like #define O_MODERN 4 /* or whatever */ #define O_RDONLY (_FREAD|O_MODERN) #define O_WRONLY (_FWRITE|O_MODERN) #define O_RDWR (_FREAD|_FWRITE|O_MODERN) In the libc open() stub, check O_MODERN. If set, just call the syscall. If not, call _really_ancient_compat_open or some such (which latter would be under the control of the relevant COMPAT_* option, and would perform the historical mapping) - or, maybe, just do the mapping in libc. I'm not sure it's worth it, though, just for the sake of eliminating FFLAGS() and OFLAGS(). /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
