Can you give the context you are using this snippet in? When I use it, everything looks as you expected except that #include "report.h" is retained.

That being said, there do seem to be some issues with the regex. Based on your description of what you want to accomplish, why not just use something like this:

while(my $line = <$in>) {
    $line =~ s/ .* report [s]? .* ; .* //sx;
    print $line;
}

It gives the following output:

#include <stdio.h>
#include "report.h"

void main()
{

  #ifdef CHECK_REPORT
  #endif

  #if defined (REPORT_ENABLE)
  #endif

  printf("The execution is completed\n");
}
