Subject: [PATCH] * aclocal.m4:        Added check for fcntl.h and the
 FD_CLOEXEC flag * generic/udp_tcl.c: bug #1477669 - set the close-on-exec
 flag for                      the socket to avoid child processes inheriting 
                     our sockets * configure:         Regenerated with
 autoconf 2.59 * configure.in:      Added call to project specific code. *
 tclconfig/tcl.m4:  Updated
