SSAX and SCSH

It would be nice to have SSAX work smoothly out of the box with SCSH.
I have observed the following two, perhaps not very major, issues with
SSAX 5.1:

lib/packages.scm:

  Structure `sxml-to-html-ext' is defined to open `posix-files'.  It
  seems to be a module available in Scheme48 only, and not in SCSH.
  Therefore the following warning is given when loading packages.scm:

    Warning: undefined variables
             #{Package 177 config}
             posix-files

  Any ideas on how to rewrite this structure definition to at least
  not produce the warning in SCSH?

lib/ssax-warn-vanilla.scm:

  In SCSH identifiers are case-sensitive, so "SSAX:warn" should be
  replaced with "ssax:warn" here.  Otherwise the exported binding is
  not found.  This should not cause trouble for other systems, as far
  as I can tell.

I'm hoping that these two minor annoyances could be fixed in the next
SSAX release.
