times test warnings

[Bruno Haible]

Hi Simon,

On OSF/1 5.1, with "gcc -Wall", I'm seeing these warnings:

test-times.c:63: warning: format '%ld' expects type 'long int', but argument 2 
has type 'clock_t'
test-times.c:64: warning: format '%ld' expects type 'long int', but argument 2 
has type 'clock_t'
test-times.c:65: warning: format '%ld' expects type 'long int', but argument 2 
has type 'clock_t'
test-times.c:66: warning: format '%ld' expects type 'long int', but argument 2 
has type 'clock_t'
test-times.c:67: warning: format '%ld' expects type 'long int', but argument 2 
has type 'clock_t'
test-times.c:97: warning: format '%ld' expects type 'long int', but argument 2 
has type 'clock_t'
test-times.c:98: warning: format '%ld' expects type 'long int', but argument 2 
has type 'clock_t'
test-times.c:99: warning: format '%ld' expects type 'long int', but argument 2 
has type 'clock_t'
test-times.c:100: warning: format '%ld' expects type 'long int', but argument 2 
has type 'clock_t'
test-times.c:101: warning: format '%ld' expects type 'long int', but argument 2 
has type 'clock_t'

The reason is that on this platform clock_t is 'int', which is narrower than
the 'long int' expected by printf.

This patch fixes it. OK to push?

        'long int'.
