* REVISION HISTORY
- * 1999-04 V0.9 Mark Martinec
- * - initial version, some modifications after comparing printf
- * man pages for Digital Unix 4.0, Solaris 2.6 and HPUX 10,
- * and checking how Perl handles sprintf (differently!);
- * 1999-04-09 V1.0 Mark Martinec <mark.martinec@ijs.si>
- * - added main test program, fixed remaining inconsistencies,
- * added optional (long long int) support;
- * 1999-04-12 V1.1 Mark Martinec <mark.martinec@ijs.si>
- * - support the 'p' conversion (pointer to void);
- * - if a string precision is specified
- * make sure the string beyond the specified precision
- * will not be referenced (e.g. by strlen);
- * 1999-04-13 V1.2 Mark Martinec <mark.martinec@ijs.si>
- * - support synonyms %D=%ld, %U=%lu, %O=%lo;
- * - speed up the case of long format string with few conversions;
- * 1999-06-30 V1.3 Mark Martinec <mark.martinec@ijs.si>
- * - fixed runaway loop (eventually crashing when str_l wraps
- * beyond 2^31) while copying format string without
- * conversion specifiers to a buffer that is too short
- * (thanks to Edwin Young <edwiny@autonomy.com> for
- * spotting the problem);
- * - added macros PORTABLE_SNPRINTF_VERSION_(MAJOR|MINOR)
- * to snprintf.h
- * 2000-02-14 V2.0 (never released) Mark Martinec <mark.martinec@ijs.si>
- * - relaxed license terms: The Artistic License now applies.
- * You may still apply the GNU GENERAL PUBLIC LICENSE
- * as was distributed with previous versions, if you prefer;
- * - changed REVISION HISTORY dates to use ISO 8601 date format;
- * - added vsnprintf (patch also independently proposed by
- * Caolan McNamara 2000-05-04, and Keith M Willenson 2000-06-01)
- * 2000-06-27 V2.1 Mark Martinec <mark.martinec@ijs.si>
- * - removed POSIX check for str_m<1; value 0 for str_m is
- * allowed by ISO C99 (and GNU C library 2.1) - (pointed out
- * on 2000-05-04 by Caolan McNamara, caolan@ csn dot ul dot ie).
- * Besides relaxed license this change in standards adherence
- * is the main reason to bump up the major version number;
- * - added nonstandard routines asnprintf, vasnprintf, asprintf,
- * vasprintf that dynamically allocate storage for the
- * resulting string; these routines are not compiled by default,
- * see comments where NEED_V?ASN?PRINTF macros are defined;
- * - autoconf contributed by Caolan McNamara
- * 2000-10-06 V2.2 Mark Martinec <mark.martinec@ijs.si>
- * - BUG FIX: the %c conversion used a temporary variable
- * that was no longer in scope when referenced,
- * possibly causing incorrect resulting character;
- * - BUG FIX: make precision and minimal field width unsigned
- * to handle huge values (2^31 <= n < 2^32) correctly;
- * also be more careful in the use of signed/unsigned/size_t
- * internal variables - probably more careful than many
- * vendor implementations, but there may still be a case
- * where huge values of str_m, precision or minimal field
- * could cause incorrect behaviour;
- * - use separate variables for signed/unsigned arguments,
- * and for short/int, long, and long long argument lengths
- * to avoid possible incompatibilities on certain
- * computer architectures. Also use separate variable
- * arg_sign to hold sign of a numeric argument,
- * to make code more transparent;
- * - some fiddling with zero padding and "0x" to make it
- * Linux compatible;
- * - systematically use macros fast_memcpy and fast_memset
- * instead of case-by-case hand optimization; determine some
- * breakeven string lengths for different architectures;
- * - terminology change: 'format' -> 'conversion specifier',
- * 'C9x' -> 'ISO/IEC 9899:1999 ("ISO C99")',
- * 'alternative form' -> 'alternate form',
- * 'data type modifier' -> 'length modifier';
- * - several comments rephrased and new ones added;
- * - make compiler not complain about 'credits' defined but
- * not used;
