Fortunately for gl_FragDepth there is an OpenGL ES extension:
http://www.khronos.org/registry/gles/extensions/EXT/EXT_frag_depth.txt

It is supported by:
- 2 mobile devices: Marvell Armada 1000 88DE3010 Berlin and Marvell ARMADA
1500 Berlin
- 100% of desktops (first mention in the shader object around 2002,
supported onwards from GLSL version 1.10)
