One further piece of information.

Luajittex for x86_64-solaris compiles fine on both version 10 and 11.
The problem is that it fails to work on version 10.

I then checked the properties of luajittex as compiled on Solaris 11:

> pvs luajittex
        libsocket.so.1 (SUNW_1.4);
        libresolv.so.2 (SUNW_2.2.2);
        libnsl.so.1 (SUNW_1.7, SUNWprivate_1.1);
        libm.so.2 (SUNW_1.2);
        libc.so.1 (SUNW_1.23, SUNWprivate_1.1);

This in principle means that the binary should run just fine on
version 10. And indeed it happily "works":

solaris10> ./luajittex --version
This is LuajitTeX, Version 0.95.0 (TeX Live 2016)

Execute  'luajittex --credits'  for credits and version details.

The problem is consistent with the binary compiled on Solaris 10 though:

solaris10> ./luajittex --luaonly
Can't create the Lua state.
Segmentation Fault (core dumped)

as opposed to:

solaris11> ./luajittex --luaonly
No script file given

or

solaris10> ./luatex --luaonly
No script file given

(also with luatex compiled on version 11).


I wonder if we couldn't perhaps make luajittex a symlink to luatex on
platforms where luajittex is missing or broken :) :) :)

improvements for the way it is used in ConTeXt and I bet nobody would
even notice. On the other hand there's hardly any need to actually run
luajittex manually.

We could in principle ship a luajittex binary that would work on
Solaris 11 and would be broken on Solaris 10, but then format
generation on Solaris 10 would cause headaches (which is probably not
something we want).

(PS: Just for fun I might try to build luajittex on Solaris 10 and see
if that same binary works on Solaris 11.)
