| | | | | | | | | | | | | | | An incorrectly-sized allocation was being made due to an incorrect argument to the `sizeof' operator. Obvious, because it violated the `foo = malloc(sizeof(*foo))' idiom. Hard-to-see, because it was a missing `*' (`*p' versus `**p').

The legacy version is `3'. (Don't ask.) = Add support for version `4' entries in the passwd(5) database. Entries in this format are identical to version 3 entries except that all integers are stored as 32-bit integers in network byte order (big endian). = pwd_mkdb is updated to generate both version 3 and version 4 entries.

| | | | | | | | | | | | | | | | | | | | | - We used to round long double arguments to double. Now we print them properly. - Bugs involving '%F', corner cases of '#' and 'g' format specifiers, and the '.*' precision specifier have been fixed. - Added support for the "'" specifier to print thousands' grouping characters in a locale-dependent manner. - Implement the __vfprintf() side of hexadecimal floating point support.

| | | | | | | | | | | | | - __vfprintf()'s 'buf' has never been used for floating point, so don't define it in terms of (incorrect) constants describing floating point numbers. The actual size needed depends on sizeof(uintmax_t) and locale details, so I slightly overestimated. - We don't need a 308-character buffer to store the string "308".
