[ANN] luaposix 34.0.4 released

["Gary V. Vaughan" <gary@...>]

A library binding various POSIX APIs. POSIX is the IEEE Portable 
Operating System Interface standard. luaposix is based on lposix.

I am happy to announce release 34.0.4 of luaposix. This release fixes 
compatibility with macOS `_POSIX_TIMERS` macro, and some specl
incompatibility for non-Linux hosts. If 34.0.2 and 34.0.3 do not fail
immediately for you with `require`, then you don't need this fix and
can skip this release.

If you have moved to the new low-level APIs, and don't rely on the Lua 
backwards compatibility layer and convenience functions, you can safely 
omit those dependencies and use the C layer only.

luaposix's home page is at https://github.com/luaposix/luaposix/, with 
documentation at https://luaposix.github.io/luaposix.


## Noteworthy changes in release 34.0.4 (2018-02-20) [stable]

### Bugs Fixed

  - `posix.time.clock_getres`, `posix.time.clock_gettime`
    `posix.time.CLOCK_MONOTONIC`, `posix.time.CLOCK_REALTIME`,
    `posix.time.CLOCK_PROCESS_CPUTIME_ID` and
    `posix.time.CLOCK_THREAD_CPUTIME_ID` are all properly elided
    on macOS again.

  - `spec/spec_helper.lua` now looks in the correct objdir
    for object modules built by luke, instead of hard-coding
    `./linux/?.so`, so specl examples work on macOS and others
    again.
