GCC #pragma to stop compilation

Is there a GCC pragma directive that will stop, halt, or abort the compilation process?

I am using GCC 4.1, but I would want the pragma to be available in GCC 3.x versions also.

You probably want #error:

$ cd /tmp
$ g++ -Wall -DGoOn -o stopthis stopthis.cpp
$ ./stopthis

Hello, world

$ g++ -Wall -o stopthis stopthis.cpp

stopthis.cpp:7:6: error: #error I had enough

File stopthis.cpp

#include <iostream>

int main(void) {
  std::cout << "Hello, world\n";
  #ifndef GoOn
    #error I had enough
  #endif
  return 0;
}

I do not know about a #pragma, but #error should do what you want:

#error Failing compilation

It will terminate compilation with the error message "Failing compilation".
