e395879b76 write: Support for MSVC 9.
* lib/unistd.in.h (write): Replace also when GNULIB_UNISTD_H_NONBLOCKING
is not 1.
* lib/write.c (write_nothrow): New function.
(rpl_write): Define also when GNULIB_NONBLOCKING or GNULIB_SIGPIPE is
not 1. Use write_nothrow.
* m4/write.m4 (gl_FUNC_WRITE): Replace read if the platform has an

73899ad375 Support non-blocking pipe I/O in write() on native Windows.
* lib/write.c (rpl_write): Split a write request that failed merely
because the byte count was larger than the pipe buffer's size.
* doc/posix-functions/write.texi: Mention the problem with large byte
counts.
