skippable build error "when binding SB-IMPL::START"

[holtzermann17]

commit: 182c18
Build system: i386-apple-darwin17.7.0
SBCL: 1.4.11.68-9456dfc60

I've run autoconf, ./configure and make. I get the following error. I pressed "1" to ignore the error and continue. That looks to have gotten me through the build process but it seemed worth reporting in any case.

This came up again later (twice similar to this).
