4659If this symbol is defined (by default it is not), then all identifiers
4660will have static linkage. This means that libev will not export any
4661identifiers, and you cannot link against libev anymore. This can be useful
4662when you embed libev, only want to use libev functions in a single file,
4663and do not want its identifiers to be visible.
4664
4665To use this, define C<EV_API_STATIC> and include F<ev.c> in the file that
4666wants to use libev.
