Hi Slava,
I tried using STRUCT: instead of C-STRUCT: in vm.factor, but this
generates a bootstrap error on loading the vocab. The problem seems to
occur when using the 'zone' struct in the 'vm' struct. If I replace '{
nursery zone }' with '{ nursery cell[4] } then it builds fine.
(file and error pasted below)
I guess this is a dependency issue: vm.factor is loaded before the
compiler starts compiling. Is there a way around this? I guess if
C-STRUCT is going soon then I'll need to do the above cell[4] hack.
Thanks,
Phil
