 Hello,
 
 I believe that the vxworks port has been reworked from scratch more or  
 less on the gcc cvs mainline. Would it be possible for someone to check  
 whether this problem still occurs when cross-compiling using cvs gcc?  
 Thanks,
 
 Dara

 Hi,
 I'm experiencing the same problem with:
 vxWorks 5.4
 binutils 2.13.2.1
 gcc 3.2.3
 
 The compiler I'm using to compile (!) is gcc-3.2.2 on a Mandrake box.
 I'm available to make other tryies.
 Following the error (just the latest step.if you need more just ask).

    No feedback 3 months, bootstrap problem with old version.
    But this one looks specific and testable.  Does anyone have a Vxworks system, so they can check that fixincludes does the right thing now?

>Organization:
>Environment:
Host compiler gcc-2.95.3, Debian 2.2
>Description:
When cross-compiling gcc 3.0 for a vxworks target, it
copies the include files that come with VxWorks and runs
fixincludes on them. The latter changes all the occurrences
of "CPU" to "__CPU__" in those files. However, after this
change one of the files stops compiling. This file defines
CPU_FAMILY according to the definition of CPU. (The latter
is defined by the compiler -- it's in the spec file for the
platform.) Here's a snippet from vxCpu.h:

#if     (CPU==I80386 || CPU==I80486 || CPU==PENTIUM || CPU==PENTIUMPRO)
#define CPU_FAMILY      I80X86
#endif  /* CPU_FAMILY==I80X86 */

fixincludes changes "CPU" to "__CPU__", and the above code
naturally stops working. At the end of vxCpu.h, there's
this code:

#if !defined(CPU) || !defined(CPU_FAMILY)
#error CPU is not defined correctly
#endif

Due to the fixincludes "fixes", this error is always
triggered. The gcc build thus fails:

>How-To-Repeat:
cd gcc-3.0
./configure --target=powerpc-wrs-vxworks --with-headers=/net/tornado/c/Tornado/target/h

The same process works flawlessly when compiling gcc 2.95.3.
