The main difference to Linux you have to look out for is the different
calling convention and how the registers are used:

So the job is typically to rearrange the register usage and to
account for the only four registers used for the first arguments
to a function, rather than the 6 registers in the SYSV ABI.
I might give it a try at some point, but I'm not highly motivated
someone who really cares about clisp steps forward to help.  I'll
concentrate first on seeing if I can get some 64-bit version of
clisp built
without ffcall.
Should be doable without.

Yes, it seems to be.  So far I've built and am testing a version with no
non-default modules, and with the default regexp module disabled.  I had
to do the latter because of the gcc problem I encountered while trying
to compile regexi.c:

The same sort of error occurs with several other modules.

I tried to test my build by using it to build xindy. It appeared to work, as far as it went, but it didn't go too far because xindy requires the regexp module. So I think I'm stuck until the gcc problem is resolved.

I don't whether it's worth uploading my crippled clisp at this point to let it get some testing. Reini, is clisp without regexp at all useful?
