Re: GNU Guile 3.0.9rc1 available for testing!

My second approach is using the rc tarball in pkgsrc.  I had to patch
out the verify call.  pkgsrc already works around PaX issues mostly, via
paxctl on things that do jit, after build and before use, and by

  -  data = mmap (NULL, len, PROT_READ, MAP_PRIVATE, fd, 0);
  +  data = mmap (NULL, len, PROT_READ | PROT_WRITE, MAP_PRIVATE, fd, 0);
     if (data == MAP_FAILED)
       SCM_SYSERROR;
     *is_read_only = 1;

because (something like, am fuzzy) mprotect (at least ours) can only
reduce not add permissions.  I still don't understand why this isn't a
more widespread issue.

With the rc tarball, the build almost works, and now stops at:

with or without -j2.   I see ice-9/readline.scm in git but not in the
rc tarball.
