1 To build, gmake is required, as is a compiler that supports C99, or at least the
2 subset of C99 that these tools make use of. Most modern compilers should work.
4 A POSIX environment is also required. These should port rather easily to other
5 environments. The most onerous requirement is probably that seeking beyond the
6 end of a file is expected to work and create a hole that will be interpreted as
7 zeroes. Patches to support non-POSIX environments are welcome.
