I have just released tftp-hpa 0.29: ftp://ftp.kernel.org/pub/software/network/tftp/ Changes in 0.29: Posixly correctness. Now compiles and runs on Win32 systems using Cygwin (http://www.cygwin.com/). (<http://www.cygwin.com/>). Fixed a bug which could cause a standalone server to exit with a "recvfrom: Interrupted system call" log message if signals arrive at a particularly inopportune moment. Fix a macro substitution bug (thanks to Richard Nyberg.)
