I'm having problems building X11R6.3 on an HP Series 400 machine with the 
gcc compiler package.  Essentially I enter the make world command and get 
the following error message in the log:

gcc -o ccimake  -O -I../../include -I../../imports/x11/include/X11  
ccimake.c
gcc -c  -O -I../../include -I../../imports/x11/include/X11  `./ccimake` 
imake.c
gcc -o imake imake.o
make[2]: Leaving directory `/data/temp/xc/config/imake'
rm -f ./config/makedepend/Makefile.proto

-DCURDIR=./config/makedepend Imakefile.c 
In file included from config/cf/Imake.tmpl:1178,
                 from Imakefile.c:8:

  Stop.

Now the above error message is coming from the following Imakefile
(Line numbers provided by vi):

     1  XCOMM $XConsortium: Imakefile /main/25 1996/09/28 16:14:57 rws $

     6  XCOMM Some compilers generate fatal errors if an -L directory does
     7  XCOMM not exist.  Since BUILDLIBDIR may not exist yet suppress its 
use.

    23  #ifdef PostIncDir
    24  POSTINCDIR = PostIncDir
        ...

Note that on line 16 and others, I have "escaped" quotes.  This is where I 
think the problem lies.  I know that in ansi compiles backslashes are not 
allowed inside quoted strings and the end of line 16 does just that.  
However, I'm not sure what to do about it.  I know that X11R6 has been 
compiled on other platforms using gcc so I know that it should compile clean 
"as is" with gcc.  My problem is that I don't know what compiler options 
should be used (for example -traditional or -ansi) to get it to get around 
this problem.  

If anyone can offer guidance or words of wisdom, I'd be very grateful!
