Gnulib module: select
@item
On Windows platforms (excluding Cygwin), error codes for @code{accept} are not
placed in @code{errno}, and @code{WSAGetLastError} must be used instead.
+@item
+This function fails when the @code{nfds} argument is 0 on some platforms:
+Interix 3.5.

Portability problems not fixed by Gnulib:
On BeOS, @code{select} can only be called on descriptors created by the
@code{socket} function, not on regular file descriptors.
@item
+On Solaris 2.6 and older, @code{select} applied to a file descriptor opened
+for reading and associated with @code{/dev/null} hangs, waiting for input,
+when instead it should return immediately.
+@item
On Linux, when some file descriptor refers to a regular file, @code{select}
may fail, setting @code{errno} to @code{EBADF}.
