Hi Alex,

I got my recent email back as “base64", but it looks fine here:

Anyway, I post it again, in a (hopefully) cleaner version:

I think I’ve found the explanation for the "constant size” error here, it’s 
about "clang":
... and I can confirm the clang-link:
$ ls -la /usr/bin/
lrwxr-xr-x     1 root   wheel         5 Apr  8 11:47 cc -> clang

Can this be fixed in picoLisp/src/Makefile, or do I have to take care of the 
unlinking myself?

This is a really stupid warning! Can probably easily switched off. The C
code is perfectly legal and exactly intended this way.

main.c:711:34: error: fields must have a constant size: 'variable length ar=
ray in structure' extension will never be
     struct {any sym; any val;} bnd[length(y)+2];

I don't know why Apple's development system has problems with this :(
Variable length structures are part of the C language since eons. No way
to fix this, because PicoLisp all over depends on such data structures.
