Subject: (test_long_long): Exercise
X-Git-Url: https://git.hcoop.net/bpt/guile.git/commitdiff_plain/b313d73a1916517e06abbd07c2080b809a51b415?ds=sidebyside

(test_long_long): Exercise
out-of-range errors on various cases.
(test_ulong_long): New function, split from test_long_long and
similarly exercising out-of-range.
