POSIX is followed in handling of local numeric formats for input, output, and number/string conversions. Multibyte detection has been improved. Handling of 'close' was made more POSIX-compliant for POSIXLY_CORRECT. Automake was updated to 1.7.5. configure.in was renamed to configure.ac. C-style switch statements are available, but must be enabled at compile time via 'configure --enable-switch'. %c always prints no more than one character whatever precision is provided. strtonum(<number>) now works again. gettext was updated to 0.12.1. Historical practice and POSIX is followed for the return value of 'rand': it's now 0 <= N < 1.
