greeter.c and signal.h

[jacob berkman <jacob ximian com>]

for some reason tinderbox is dying on greeter.c:

    greeter.c: In function `main´:
    greeter.c:580: storage size of `hup´ isn´t known
    greeter.c:627: `SIGCHLD´ undeclared (first use in this function)
    greeter.c:627: (Each undeclared identifier is reported only once
    greeter.c:627: for each function it appears in.)
    greeter.c:629: `SIGHUP´ undeclared (first use in this function)
    greeter.c:632: `SIGINT´ undeclared (first use in this function)
    greeter.c:635: `SIGTERM´ undeclared (first use in this function)
    greeter.c:644: `SIG_SETMASK´ undeclared (first use in this function)
    gmake[4]: *** [greeter.o] Error 1

if anyone knows why this came about, let me know.  i just added an
#include <signal.h> to greeter.c in the mean time...
