[RFA] Add "." to %load-path for guile 1.8.

[Doug Evans <dje@sebabeach.org>]

Hi.

Guile 1.8 removed "." from %load-path so "guile -s ../relative/path/foo.scm"
no longer works, and this breaks cgen.

Tested with guile 1.4.1 and 1.8.5 on m32r binutils.

If someone has a strong opinion on solving this differently,
please speak up.

[For completeness' sake,
While I myself trip over the "info" command's distinction between
"info -f foo" and "info -f ./foo" from time to time, I wonder if
Guile shouldn't treat relative paths separately as well.  But we still
have to cope with 1.8.x of course.]

	* guile.scm: Add "." to %load-path if >= guile version 1.8.
