Architectures like SPARC do not allow unaligned accesses. Avoid them by
memcpy()ing the data to an aligned buffer. On x86 systems where
unaligned loads are fast, the memcpy() will be compiled away and the
same code generated as before.
- adds man page to `EXTRA_DIST`
- `configure` checks for `a2x` only if the man page does not exist (poor
mans way of checking if we build from git or release tarball)
- fixes#50
Unfortunately, a2x generates the manpage only in the directory where the
source file is located and it does not offer a command line option to
change the output directory. I hope, the `if ! test -f` hack I
implemented works everywhere.
- `__APPLE__` vs `__OS2__` - does this actually work? Would some please test on apple and give feedback?
- pthread via `AX_PTHREAD`
- version via `PACKAGE_VERSION` in `config.h`
- large file support via `AC_SYS_LARGEFILE`
