[Bug c/17070] New: unnecessary quote check by preprocessor

[tosa at nmr dot mgh dot harvard dot edu]

I get the following error:
minerva:/home/ytosa/c>gcc -g -o multiline multiline.c
multiline.c:13:10: missing terminating " character
multiline.c:16:5: missing terminating " character
(see the code at the end).

I thought that using the preprocessor making it safe to
use the multiline text for gcc < 3.3.x.
But it makes it broken under gcc 3.3.3.
 
Actually, the preprocessor does the correct thing except
the quotes.  -E produced the following:

int main(int argc, char *argv[])
multiline.c:13:10: missing terminating " character   
multiline.c:16:5: missing terminating " character    
{
  printf("No multiline allowed\n");

  return 0;
}

------------------------------- starts here
#include <stdio.h>

#ifdef __GNUC__
#define GCC_VERSION (__GNUC__ * 10000 \
                     + __GNUC_MINOR__ * 100 \
                     + __GNUC_PATCHLEVEL__)
#endif

int main(int argc, char *argv[])
{
#if GCC_VERSION < 30300
  printf(
         "
  Multiline text1
  Multiline text2
  \n");
#else
  printf("No multiline allowed\n");
#endif
  return 0;
}
