Yes. I wonder, though, if we should go one further and create a program like
#include <stdio.h>
int main(void) {
printf("%u\n", (unsigned) sizeof(long));
}
which prints 4 and 8, respectively, on my 32 and 64 bit systems. I may mod it
to print
printf("-DWL=%u\n", 8*(unsigned) sizeof(long));
and that would generate the appropriate switch, also catching other 64 bit
systems and not just the Intel CPU based ones.
Or maybe test for sizeof==8 and then print 64, else print 32 as a fallback.
