testcase

Description of problem:
The following code

---------------
#define R "r"

R"bx"
---------------

causes gcc-4.4.0-0.23.x86_64 (cpp-4.4.0-0.23.x86_64) to print the following error message when compiling with

gcc -E test.c --std=gnu99
# 1 "test.c"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "test.c"
test.c:3:1: error: invalid character '
' in raw string delimiter

R"bx"

It also works with the upstream gcc 4.4 and with 4.3 gcc versions on different platforms.
