I'll try this again. Sorry about the mail problems.
This is a fix for a FIXME, in case it is desired.
It turns out my git-fu is not truly up to snuff, so I'm including the
patch in this email.
It passes the SRFI-144 tests (using Larceny) and shows improvement in
the tests in the test file test-log1p.scm (compiled using Gambit).
