- Configure process now checks if the preprocessor _REENTRANT symbol is already

  defined. If it isn't currently defined a set of checks are performed to test

  if its definition is required to make visible to the compiler a set of *_r

  functions. Finally, if _REENTRANT is already defined or needed it takes care

  of making adjustments necessary to ensure that it is defined equally for the

  configure process tests and generated config file.

- When recvfrom prototype uses a void pointer for arguments 2, 5 or 6 this will

  RECVFROM_TYPE_ARG5_IS_VOID or RECVFROM_TYPE_ARG6_IS_VOID.

- Configure process now checks availability of recvfrom() socket function and

  finds out its return type and the types of its arguments. Added definitions

  for non-configure systems config files, and introduced macro sreadfrom which

  will be used on udp sockets as a recvfrom() wrapper.
