# doubles (if supported), of machine-specific short and long
# integers, machine-specific floating point exceptions (infinity,
# not-a-number ...), of the effects of locale, and of features
# specific to multi-byte characters (under the utf8 pragma and such).

# In each of the following lines, there are three required fields:
# printf template, data to be formatted (as a Perl expression), and
# expected result of formatting.  An optional fourth field can contain
# a comment.  Each field is delimited by a starting '>' and a
# finishing '<'; any whitespace outside these start and end marks is
# not part of the field.  If formatting requires more than one data
# item (for example, if variable field widths are used), the Perl data
# expression should return a reference to an array having the requisite
# number of elements.  Even so, subterfuge is sometimes required: see
# tests for %n and %p.
#
# Tests that are expected to fail on a certain OS can be marked as such
# by trailing the comment with a skip: section. Skips are tags separated
# bu space consisting of a $^O optionally trailed with :osvers. In the
# latter case, all os-levels below that are expected to fail. A special
# tag 'all' is allowed for todo tests that should fail on any system
