Found the following implicit function declarations in configure logs:

config.log:3535 - exit

Same thing happens on 2.2.7-r1 which is currently stable, so I prepared patch on 2.2.7-r1, but also tested it on 2.2.7-r102 (mentioned in bug report). Please review if that makes sense, but seems to be working.

Issue: implicit function declaration for exit function.
Reason: Missing header which contains exit function inside configure file.
Solution: Add #include <stdlib.h>.

Upstream gnulib fixed this a different way: https://github.com/coreutils/gnulib/commit/f12a7bbb4acaaa72f48e452e04da2a4dd749a664

Both approaches work fine :) but it does demonstrate that this guile version is quite ancient!
