Hello, a week ago, I tried to build gnumach with the gcc-2.95.1 compiler. There is a lot of Linux derived code (inline assembly statements) in gnumach which is incompatible with gcc-2.95.1. The compiler will fail at nearly every __asm__ statement. Obviously, the gnumach code was derived from Linux kernel-2.0.x or earlier, because Linux kernel-2.2.x has different code which works with gcc-2.95.1 (and older compilers!). So, one day the gnumach Linux code will need the same changes. Are there any plans for this job? Or has someone already started with it? Or are there no plans for Debian to upgrade to gcc-2.95.x? Yes this is indeed something that has to be fixed. As far as I know nobody has done anything, so feel free to hack away at it yourself. If you do, please notify this list and [email protected] such that nobody else starts working on it independently. By the way, there is also Linux code in the Hurd itself (in pfinet to be specific) which probably needs some work too. As far as I saw, some timing functions for very short times were improved in kernel-2.2.x. They are in the same source files which must be updated for the new compiler. Because I suspect timing problems in gnumach (see my earlier mails), I am very much interested in any improvements here. Sorry, I don't think I can be of any help here. Mark
