+/*
+ * History
+ *
+ * 2008-01-20 Holger Weiss <holger@jhweiss.de> for C99-snprintf 1.1:
+ *
+ * Fixed the detection of infinite floating point values on IRIX (and
+ * possibly other systems) and applied another few minor cleanups.
+ *
+ * 2008-01-06 Holger Weiss <holger@jhweiss.de> for C99-snprintf 1.0:
+ *
+ * Added a lot of new features, fixed many bugs, and incorporated various
+ * improvements done by Andrew Tridgell <tridge@samba.org>, Russ Allbery
+ * <rra@stanford.edu>, Hrvoje Niksic <hniksic@xemacs.org>, Damien Miller
+ * <djm@mindrot.org>, and others for the Samba, INN, Wget, and OpenSSH
+ * projects. The additions include: support the "e", "E", "g", "G", and
+ * "F" conversion specifiers (and use conversion style "f" or "F" for the
+ * still unsupported "a" and "A" specifiers); support the "hh", "ll", "j",
+ * "t", and "z" length modifiers; support the "#" flag and the (non-C99)
+ * "'" flag; use localeconv(3) (if available) to get both the current
+ * locale's decimal point character and the separator between groups of
+ * digits; fix the handling of various corner cases of field width and
+ * precision specifications; fix various floating point conversion bugs;
+ * handle infinite and NaN floating point values; don't attempt to write to
+ * the output buffer (which may be NULL) if a size of zero was specified;
+ * check for integer overflow of the field width, precision, and return
+ * values and during the floating point conversion; use the OUTCHAR() macro
+ * instead of a function for better performance; provide asprintf(3) and
+ * vasprintf(3) functions; add new test cases. The replacement functions
+ * have been renamed to use an "rpl_" prefix, the function calls in the
+ * main project (and in this file) must be redefined accordingly for each
+ * replacement function which is needed (by using Autoconf or other means).
+ * Various other minor improvements have been applied and the coding style
+ * was cleaned up for consistency.
+ *
+ * 2007-07-23 Holger Weiss <holger@jhweiss.de> for Mutt 1.5.13:
+ *
+ * C99 compliant snprintf(3) and vsnprintf(3) functions return the number
+ * of characters that would have been written to a sufficiently sized
+ * buffer (excluding the '\0'). The original code simply returned the
+ * length of the resulting output string, so that's been fixed.
+ *
+ * 1998-03-05 Michael Elkins <me@mutt.org> for Mutt 0.90.8:
+ *
+ * The original code assumed that both snprintf(3) and vsnprintf(3) were
+ * missing. Some systems only have snprintf(3) but not vsnprintf(3), so
+ * the code is now broken down under HAVE_SNPRINTF and HAVE_VSNPRINTF.
+ *
+ * 1998-01-27 Thomas Roessler <roessler@does-not-exist.org> for Mutt 0.89i:
+ *
+ * The PGP code was using unsigned hexadecimal formats. Unfortunately,
+ * unsigned formats simply didn't work.
+ *
+ * 1997-10-22 Brandon Long <blong@fiction.net> for Mutt 0.87.1:
+ *
+ * Ok, added some minimal floating point support, which means this probably
+ * requires libm on most operating systems. Don't yet support the exponent
+ * (e,E) and sigfig (g,G). Also, fmtint() was pretty badly broken, it just
+ * wasn't being exercised in ways which showed it, so that's been fixed.
+ * Also, formatted the code to Mutt conventions, and removed dead code left
+ * over from the original. Also, there is now a builtin-test, run with:
+ * gcc -DTEST_SNPRINTF -o snprintf snprintf.c -lm && ./snprintf
+ *
+ * 2996-09-15 Brandon Long <blong@fiction.net> for Mutt 0.43:
+ *
+ * This was ugly. It is still ugly. I opted out of floating point
+ * numbers, but the formatter understands just about everything from the
+ * normal C string format, at least as far as I can tell from the Solaris
+ * 2.5 printf(3S) man page.
+ */
+
+/*
+ * ToDo
+ *
+ * - Add wide character support.
+ * - Add support for "%a" and "%A" conversions.
+ * - Create test routines which predefine the expected results. Our test cases
+ * usually expose bugs in system implementations rather than in ours :-)
+ */
+
+/*
+ * Usage
+ *
+ * 1) The following preprocessor macros should be defined to 1 if the feature or
+ * file in question is available on the target system (by using Autoconf or
+ * other means), though basic functionality should be available as long as
+ * HAVE_STDARG_H and HAVE_STDLIB_H are defined correctly:
+ *
+ * HAVE_VSNPRINTF
+ * HAVE_SNPRINTF
+ * HAVE_VASPRINTF
+ * HAVE_ASPRINTF
+ * HAVE_STDARG_H
+ * HAVE_STDDEF_H
+ * HAVE_STDINT_H
+ * HAVE_STDLIB_H
+ * HAVE_INTTYPES_H
+ * HAVE_LOCALE_H
+ * HAVE_LOCALECONV
+ * HAVE_LCONV_DECIMAL_POINT
+ * HAVE_LCONV_THOUSANDS_SEP
+ * HAVE_LONG_DOUBLE
+ * HAVE_LONG_LONG_INT
+ * HAVE_UNSIGNED_LONG_LONG_INT
+ * HAVE_INTMAX_T
+ * HAVE_UINTMAX_T
+ * HAVE_UINTPTR_T
+ * HAVE_PTRDIFF_T
+ * HAVE_VA_COPY
+ * HAVE___VA_COPY
+ *
+ * 2) The calls to the functions which should be replaced must be redefined
+ * throughout the project files (by using Autoconf or other means):
+ *
+ * #define vsnprintf rpl_vsnprintf
+ * #define snprintf rpl_snprintf
+ * #define vasprintf rpl_vasprintf
+ * #define asprintf rpl_asprintf
+ *
+ * 3) The required replacement functions should be declared in some header file
+ * included throughout the project files:
+ *
+ * #if HAVE_CONFIG_H
+ * #include <config.h>
+ * #endif
+ * #if HAVE_STDARG_H
+ * #include <stdarg.h>
+ * #if !HAVE_VSNPRINTF
+ * int rpl_vsnprintf(char *, size_t, const char *, va_list);
+ * #endif
+ * #if !HAVE_SNPRINTF
+ * int rpl_snprintf(char *, size_t, const char *, ...);
+ * #endif
+ * #if !HAVE_VASPRINTF
+ * int rpl_vasprintf(char **, const char *, va_list);
+ * #endif
+ * #if !HAVE_ASPRINTF
+ * int rpl_asprintf(char **, const char *, ...);
+ * #endif
+ * #endif
+ *
+ * Autoconf macros for handling step 1 and step 2 are available at
+ * <http://www.jhweiss.de/software/snprintf.html>.
