[Bug preprocessor/20907] New: long comments throw off line numbers

[dpatel at apple dot com]

It seems that long comment blocks can throw off gcc's notion of the source line 
number. Here is a 
sample test case (also attached in case the line breaks get messed up pasting 
in):
/*
This is a really long comment. This is a really long comment. This is a really 
long comment. This is a 
really long comment. This is a really long comment. This is a really long 
comment. This is a really long 
comment. This is a really long comment. This is a really long comment. This is 
a really long comment. 
This is a really long comment. This is a really long comment. This is a really 
long comment. This is a 
really long comment. This is a really long comment. This is a really long 
comment.
 */
#warning test warning
#include <stdio.h>

int main(int argc, char *argv)
{
        printf("This is line %d\n", __LINE__);
}
