Subject: Remove bogus note about flo:compare and flo:safe-compare.
X-Git-Tag: mit-scheme-pucked-10.1.7~3^2~87
X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=a10c3fb0aa111947d24c41361abbc76065fe9b5d;p=mit-scheme.git

Remove bogus note about flo:compare and flo:safe-compare.

Never actually committed these; decided a four-way comparison wasn't
worth it without a motivating application.  Won't work for anything
that expects a three-way -1/0/+1 compare.
