wingo pushed a commit to branch stable-2.0
in repository guile.
commit 2247a56d5dab1a9fde1c66f73116e7fa8257607f
Author: Andy Wingo <address@hidden>
Date: Mon Jul 11 22:17:09 2016 +0200
Provide `kill' only if supported by the host
* libguile/posix.c (scm_kill): Only provide if the host has `kill'. An
incompatible change on MinGW, where this function would work only if
the PID was the current PID, but that will be fixed by the next
process.
