[M3devel] libXaw.so.6 again

[microcode at zoho.com]

I think this could be solved by static linking mostly, but there could still be problems with libc/glibc as I found out with FPC recently. Surely somebody who knows UNIX/Linux ought to be able to figure a way around this.

Hi all:
'forwards compatibility' is not achieved by any of OSes because of Gcc merits as it should be, but backwards also don't say a word as expected, mainly due "security issues", so I don't know if commercial *ix are, at least have the sources should make that easier I guess; I once tried to compile a virtual machine package and I was told that first find my distro's 'minimum common factor' and cross-compile to that system and then recompile everything on it, but I solved hacking the virtual machine sources, so my guess is that you can have 'forwards compatibility' if you can get a sufficient old version of your tool chain and OS to cross-compile from newer.
Modula-3 had this nice thing of emitting the "assembly sources" and emit native code for the platform in-situ and relink everything (so sort of eliminate the requisite of having an older compiler, but just native gcc nice to do). Maybe this would be a nice to have item for next releases, wouldn't be?
Thanks in advance

Apparently free/open Unices (Linux, OpenBSD, FreeBSD, NetBSD) have no binary compatibility.
I find this very surprising, crazy, disappointing, but apparently true.
We must distribute source to achieve the usual expected portability.
 C source at that, to achieve the usual expected buildability.
Or maybe I'm confused.
The various commerical systems (Solaris, AIX, Irix, VMS, Windows, Darwin, HP-UX) do/did not have this problem.
