Use -1 instead of EOF for an invalid file descriptor
...
The POSIX standards specify that the open() and openat() functions
technically return -1, not EOF, on failure -- even though most (perhaps
all) systems define EOF to be -1!

Eliminate a TOCTOU bug between data_directory() and xmkdir()
...
Checking the presence of the traditional data directory using stat()
leads to a time-of-check / time-of-use bug by the time it is possibly
created using xmkdir(). Use file descriptors and openat() to work around
this problem.

Convert xstrfmon() into a wide-character version xwcsfmon()
...
Also work around buggy implementations of strfmon() that do not copy
complete multibyte sequences that may be part of a locale's
mon_thousands_sep, thousands_sep, mon_decimal_point or decimal_point.

Rename l_strfmon() and rewrite as xstrfmon() to handle POSIX locale better
...
Current and previous versions of ISO/IEC 9945-1 (POSIX), particularly SUSv3
(2001) and SUSv4 (2008), require strfmon() to return rather meaningless
strings when used with the POSIX "C" locale. In particular, the standard
POSIX locale does not define a currency symbol, a monetary radix symbol
(decimal point) or a negative sign. This means strfmon(..., "%n", -123.45)
is supposed to produce "12345" instead of something like "$-123.45"!
The new xstrfmon() overcomes these limitations by using snprintf() as
appropriate.

Minor clean-up: replace character constants with wide-char versions
...
Wide-char character constants is not strictly needed for most (all?)
modern C compilers, as ASCII maps to wchar_t directly (as long as
__STDC_ISO_10646__ is defined). However, it doesn't hurt to be pedantic!
