Specifically:

| A definition of [IOV_MAX] shall be omitted from <limits.h> on 
specific
| implementations where the corresponding value is equal to or greater 
than
| the stated minimum, but is unspecified.
|
| This indetermination might depend on the amount of available memory 
space on
| a specific instance of a specific implementation. The actual value 
supported
| by a specific instance shall be provided by the sysconf() function.

> Not sure if Android is wrong there.

Both Android and VLC are broken: Android because the value is *not* 
unspecified and VLC because it assumes IOV_MAX is specified.
