This might save someone a few seconds -- in cygwin if you
use scm_listofnull, the loader can complain:
variable '_scm_sys_protects' can't be auto-imported.
I got around it by using scm_cons(SCM_EOL, SCM_EOL) in place
of scm_listofnull.

scm_sys_protects need to be declared "__declspec (dllexport) extern" in
the Guile root.h header file. CVS claims this has been in place since
November 2001, but I don't see it in Guile 1.6.1. Curious...
For the time being, if you put
#if (defined(_WIN32) || defined(__CYGWIN__))
__declspec (dllexport) extern scm_sys_protects;
#endif
early in your application code, you should be able to use scm_listofnull
(and friends) as normal. (I ended up having to do this for several
other global variables as well when I was compiling to cygwin.)
