No, 0.9 did not work for Solaris; 0.9b will. I had to solve several problems: 
missing functions (setenv), different integer type names (u_int8_t -> 
uint8_t), and some other tweaks. However, this port revealed one memory leak 
in "dpp", and I am glad to see that the source code of ECL slowly converges 
to something really portable. You will have to wait, though, until I announce 
the port, because I still have to make sure that I did not break anything in 
the other supported platforms.

Yes. --disable-shared tells ECL that it should not produce dynamically linked 
libraries for lisp code; the LDFLAG="-static" ensures that all other 
libraries (i.e. non-lisp) are statically linked in the program.

They will not be: ECL itself is just about 800k; ECL plus the C library is 
about 1200k in my SuSe 8.2 (i586); the compiler adds an overhead of about 
300k.
