bug#11781: compilation failure: `ULLONG_MAX' undeclared

[Dan Nicolaescu]

On an ancient machine (don't ask) building the trunk fails:

gcc -c  -Demacs -DHAVE_CONFIG_H  -I. -I/tmp/emacs/src -I../lib 
-I/tmp/emacs/src/../lib   -I/usr/X11R6/include            -MMD -MF 
deps/sysdep.d -MP     -g -O2 /tmp/emacs/src/sysdep.c
/tmp/emacs/src/sysdep.c: In function `time_from_jiffies':
/tmp/emacs/src/sysdep.c:2587: `ULLONG_MAX' undeclared (first use in this 
function)
/tmp/emacs/src/sysdep.c:2587: (Each undeclared identifier is reported only once
/tmp/emacs/src/sysdep.c:2587: for each function it appears in.)
