Oops - yes, I got confused about the highlevel macros: the SDL support 
code itself doesn't use them, but the little sdl-csi program does; the 
heap-nodes, though, are part of the SDL timer implementation.

Thank you! You're right - that fixes it. I simply recompiled my current 
darcs checkout in place (after doing a full clean and manually removing 
all *.c files (except runtime.c of course)) and now the SDL egg compiles 
and runs fine.

Some srfi-13-related problem does seem like a likely explanation. While 
I was waiting for chicken to rebootstrap itself, I dusted off my old 
docscm tool, which uses srfi-13, and while it compiled OK it died with 
that same error ("Error: call of non-procedure: #<unbound value>") when 
I ran it. Recompiling with the newly bootstrapped chicken, everything 
works fine.
