wingo pushed a commit to branch lightning
in repository guile.
commit b279feb7c580dabfa6014e41060b1d22fd119712
Author: pcpa <[email protected]>
Date: Mon Sep 9 19:19:45 2013 -0300
Add fallback logic instead of error if cannot figure __WORDSIZE.
This was an issue on FreeBSD 8.x, and the logic used is the same as
FreeBSD 9.1 stdint.h.
