I have an application that I wrote for X 10 a while back that I
now need to run on the Sun 4. Is anyone anywhere aware of a
publicly available port of X 10 (revision 4) to the Sun 4. Please
reply by mail, I will summarize to the net if I get anything interesting.
--- Thanks in advance

I need a port of the X 10 revision 4 SERVER to the Sun 4. If anyone has any pointers to a publicly available port, or has information suggesting that the Sun 3 server runs fine on the Sun 4 please let me know. Please respond by mail, I will summarize to the net. --- Thanks for your help --- Bill.

The consensus is that the version of libsun.a the sources of which
are available from oberon.usc.edu runs on the Sun 4. Some people
suggested that the Sun 3 server could be made to work with only trivial,
obvious changes (if that). Finally, one person suggested that there is
a problem compiling the X server under SUN OS 4.0 --- Something about
the code assuming that locals are initialized to 0, and the compiler
not so initializing them.

I know of no compilers that so initialize them. It just so happens that on UNIX implementations, when stack pages are created they are filled with zeroes, which means that the *first* time you use a stack page, the locals are likely to be zero. Unfortunately, in SunOS 4.0, "main()" and its descendents are usually *not* the first guys to use the first stack page or so; the run-time loader gets there first, and the result is that they aren't filled with zeroes when "main()" and procedures it calls use them. Neither the C language nor UNIX guarantee that locals will be initialized to any particular value - and, if some routine is called more than once, there is a good chance that they will *not* be initialized to zero on calls after the first.
