Write a C program that prints "true" if the compiler handles nested comments, and "false" if not.

How about this? I'm not sure if a non-nested-comment compiler will accept it, though, because of the */ left over at the end.
int main() {
int a = 1;
/* /**/ a = 0; /**/ */
if(a == 1) { printf("true"); }
else printf("false");
return 1;
}

int nested(){
return 1/* /**/ *0*/*1* /**/1;
}
if nested:
return 1/* /**/ *0*/*1* /**/1;
return 1*1* 1;
if not nested:
return 1/* /**/ *0*/*1* /**/1;
return 1 *0*1;

Another approach:
char *truth = /* /* */ " */ " /* " /* */;
if nested comments work, truth = " /* "
if they don't, truth = " */ "
