how multi-line strings handled in gcc-4.0.0?

[cyclops <cyclops64 at gmail dot com>]

Dear all,

We have ported gcc-3.2.3 to our target machine successfully about one year ago. 

Now we are trying to upgrade it from 3.2.3 to 4.0.0.

I found that some files like cpplex.c disappeared from 4.0.0. (Maybe
in earlier version, i do not know)

The thing is in 3.2.3, when compile code like

 __asm__ ("
           .set  noat
           mov   r5,%0
           mov   r8,%1
           mov   r9,%2
           mov   r10,%3
           svc
           .set  at"
           :
           : "r"(SVC_LSEEK), "r"(file), "r"(ptr), "r"(dir)
           : "r5", "r8", "r9", "r10"
           );


It only gives an warning:  "warning: multi-line string literals are
deprecated". The code is still generated correctly.

However, in gcc-4.0.0, it treats the same piece code as error:

"error: missing terminating " character"

I know this problem can be solved by add "\" at the end of each line. 
However, we have a lot of code written in that way, we may not want to
change them all.  Is there a way to make gcc-4.0.0 to treat those
multi-line strings as gcc-3.2.3 did?

Thanks very much!
