+Portability problems fixed by Gnulib module @code{stdio}, together with module @code{nonblocking}:
 @itemize
+@item
+When reading from a non-blocking pipe whose buffer is empty, this function
+fails with @code{errno} being set to @code{EINVAL} instead of @code{EAGAIN} on
+some platforms:
+mingw, MSVC 9.

 Portability problems not fixed by Gnulib:
 @itemize
 @item
+C99 and POSIX.1-2001 and later require end-of-file to be sticky, that
+is, they require this function to act as if it reads end-of-file if
+@code{feof} would return nonzero.  However, on some systems this
+function attempts to read from the underlying file descriptor even if
+the stream's end-of-file indicator is set.  These systems include
+glibc and default Solaris.
+@item
 On Windows platforms (excluding Cygwin), this function does not set @code{errno}
 upon failure.
+@item
+This function crashes if the stream's file descriptor has already been
+closed, if @code{MSVC_INVALID_PARAMETER_HANDLING} is
+@code{HAIRY_LIBRARY_HANDLING} or @code{SANE_LIBRARY_HANDLING},
+on some platforms:
+MSVC 9.
