int main( int argc, char** argv )
{
   int x, y, z;

   if (argc >1)
     x = 100;
   else
     y = 200;
     z = 300;
}

gcc -std=c99 -Wall x.c
x.c: In function ‘main’:
x.c:10:3: warning: this ‘else’ clause does not guard... 
[-Wmisleading-indentation]
    else
    ^~~~
x.c:12:5: note: ...this statement, but the latter is misleadingly 
indented as if it is guarded by the ‘else’
      z = 300;

Use the tools bartc....
