Hi Wolfgang,

The context here could be either cpp or shell.  Backslash \ is a valid 
escape in all shells that are worthy of being used at denx.de (I forgot 
if you prefer bash or csh).  Either way, your statement is still 
correct, there is no file "u-boot-1.1.4includeconfigs" (or 
"u-boot-1.1.4includeconfigspxa255_idp.h" to extrapolate the question).

$ ls -l u-boot-1.1.4\include\configs\pxa255_idp.h
/bin/ls: u-boot-1.1.4includeconfigspxa255_idp.h: No such file or directory

$ touch u-boot-1.1.4\include\configs\pxa255_idp.h

$ ls u-boot-1.1.4\include\configs\pxa255_idp.h
u-boot-1.1.4includeconfigspxa255_idp.h

$ cat x.c
/*
  * Test escaping in the C compiler
  */
#include "u-boot-1.1.4\include\configs\pxa255_idp.h"

int main(int argc, char *argv[])
{
         return(0);
}

$ make x
cc     x.c   -o x
x.c:4:53: u-boot-1.1.4\include\configs\pxa255_idp.h: No such file or 
directory
make: *** [x] Error 1
