/*
* POSIX says that LONG_BIT and WORD_BIT are defined, but some notable
* non-conforming systems and compilers don't don't define it, or only
* define it in circumstances I'm unwilling to comply with (such as
* defining _GNU_SOURCE.
*
* So, unfortunately, although LONG_BIT and WORD_BIT are the most
* elegant solutions, we're forced to do this so we can check LONG_MAX
* and INT_MAX.
