Gnulib module: recvfrom

Portability problems fixed by Gnulib:
@itemize
@item
This function has the return type @code{int} instead of @code{ssize_t}
on some platforms:
OSF/1 5.1.
@item
On Windows platforms (excluding Cygwin), error codes for
@code{recvfrom} are not placed in @code{errno}, and
@code{WSAGetLastError} must be used instead.
@end itemize

Portability problems not fixed by Gnulib:
@itemize
@item
Some platforms don't have a @code{socklen_t} type; in this case this function's
sixth argument type is @samp{int *}.
