Attached is a patch to apply to guile-2.2.0 to compile on FreeBSD 11.0
Changes
1) updated README to indicate which extra FreeBSD packages need to be installed
2) minor change to configure.ac (implies autoconf needs to run) to use bdw-gc-threaded instead of bdw-gc
With this, I had successful configure, gmake, and gmake check.
