Gnulib module: stdio, sigpipe

When writing to a pipe with no readers, this function fails, instead of
obeying the current @code{SIGPIPE} handler, on some platforms:
mingw.
@end itemize

Portability problems not fixed by Gnulib:
@itemize

On Windows platforms (excluding Cygwin), this function does not set @code{errno}
