Summary: Line continuation character "\" problem

Initial Comment:
LXR Version: 0.9.8
Error message in genxref output: BTYPE was: atom
DB: mysql
Plain files.

When the code being parsed contains a line continuation character, like "\" in C, the line associated with "References:" to the tag are wrong.  For example, parsing this code (ignore the line numbers, they are included to show the problem with References)....

<<<
001 #define my_define (100 - \
002         25)
003 
004 char[] my_string;
005 
006 strcat(my_string, "Hello");
007 
008 for (i=0, i<my_define; ++i){
009         printf("The number is: %d", i);
010 }
011 
012 printf("%s", my_string);

>>>

Clicking on "my_define" results in the following. Note the line numbers in the references for "my_define" should be (1 and 8) not (1 and 7).

<<<
my_define

Declarations:
/deviceapps/aim_adams.c, line 1	macro (un)definition	

1 declarations in 1 files.

References:
  	/deviceapps/aim_adams.c, line 1
  	/deviceapps/aim_adams.c, line 7

2 references in 1 files.
>>>

Clicking on my_string results in something even stranger. There are only 3 references in the file and only one of the references displayed match the actual line number.

<<<
my_string

Declarations:
/deviceapps/aim_adams.c, line 4	variable definition	

1 declarations in 1 files.

References:
  	/deviceapps/aim_adams.c, line 3
  	/deviceapps/aim_adams.c, line 5
  	/deviceapps/aim_adams.c, line 11
  	/deviceapps/aim_adams.c, line 12

4 references in 1 files.
