There is a bug in the preprocessor of gcc 2.1 and 
gcc-1.40.

It is possible to write a #define which will generate several C lines
in the preprocessed file. This makes bad line numbers. This happens
when using a multi-lined string in a #define.

I guess the fix is for cpp to translate a mutli-lined string in a
#define into a one line string (ie use '\n').

In the example below, cpp should output :

"just\na little\nmulti-lined\nstring"; foo(x)

The following demonstrates the problem.

psi:/usr2/pierre:cat pw.c

#define FOOO x = "just
a little
multi-lined
string"; foo(x)

void
foo(char *x)
{

}

main()
{
char *x;

  FOOO;
}
psi:/usr2/pierre:gcc -E pw.c
# 1 "pw.c"






void
foo(char *x)
{

}

main()
{
char *x;

  x = "just
a little
multi-lined
string"; foo(x) ;
# 18 "pw.c"
}
