so this code is undefined for a few different reasons.
#1 is you can't call fprintf from an async signal (e.g. SIGALARM).

I have tried to merge two dhry_1.c and dhry_2.c to dhry_3.c, and do below test:
gcc -c -DTIME -Wall -pedantic -ansi -DREG=register -DHZ= -O3
-fomit-frame-pointer -fforce-addr -ffast-math -Wall dhry_3.c -o dhry_3_reg.
11 matches
