See the commit log for more.

Building environment requirements
---------------------------------

* GNU Make or BSD make.
* A C99 compiler. Some platform-specific codes may use GNU C extensions; in
  that case, GCC 3.3+ or a compatible C compiler will be required.

Supported target platforms
--------------------------

### Linux-based operating systems

A minimal of **Linux 2.0** is required; while version 2.6 or later is
recommended.

For **GNU/Linux**, **GNU C Library 2.0** and later versions are supported.

For **uC/Linux**, only the **uClibc 0.9.33.2** is supported.

For **Android/Linux**, **Android 4.0** and later versions are supported.

Linux with other C library will likely work, but not tested.

### kFreeBSD-based operating systems

A minimal of **kFreeBSD 5.0** is required.

**FreeBSD 5** and later releases are supported.

For **GNU/kFreeBSD**, only the **GNU C Library 2.13** is tested and therefore
supported.

### DragonFly BSD

**DragonFly BSD 5.0** and later releases are supported.

### macOS (Mac OS X)

**Mac OS X 10.4** and later releases are supported.

### OpenBSD

**OpenBSD 5.0** and later releases are supported.

### Solaris

**Solaris 9** and later releases are supported.

Currently only tested with GCC, therefore building with Sun C compiler is not
supported.

Other Solars-kernel-based operating systems such as **GNU/kOpenSolaris** are
currently not supported.

### GNU/Hurd

Currently tested on following versions of operating system components:
 * **GNU C Library 2.19**, **GNU HURD 0.5**, **GNU Mach 1.4**
 * **GNU C Library 2.26**, **GNU HURD 0.9**, **GNU Mach 1.8**

It is expected to work with newer versions of operating system components.

### AIX

Tested on **AIX 6.1**, **AIX 7.1** and **AIX 7.2**. Although unsupported, it
is expected to work on newer versions of the operating system.

### Haiku

**Haiku R1/alpha4** and later releases are supported.

### Cygwin

Currently only tested on **Cygwin 1.7.18**.

### Interix

Support is incomplete, many features won't work.

**Interix 3.5** and later versions are supported.
