"synchronise" is a bit tricky because support for SBCL, in particluar
content of the src/lisp subdirectory was one of first places where
build-improvements and wh-sandbox diverged in a non-trival way
(non-trival meaning that the same code was changed in two different
ways).
OTOH OpenAxiom can easily benefit from work done in wh-sandbox and
FriCAS. One easy piece is FFI support -- FriCAS FFI support is not
nice (I plan to re-stucture it) but it works and can be easily
re-used. Similarly platform-specific routines are easy to re-use.
More generally I would say that differences outside src/interp are
easily managable. In src/interp things get more tricky: OpenAxiom
has 131367 lines there, FriCAs 93913. The unified diff of common
files has 35272 lines. Most of differences is trivial, but bulk
of the diff makes hard to spot the essential ones.
I belive that FriCAS and OpenAxiom will be able for long time to
"port" improvements from one to another, but "synchronizing" both
codebases is more difficult.
