Cannot stat gcc/include-fixed/limits.h when installing GCC 4.7.2

["Patrick 'P. J.' McDermott" <pjm@xxxxxxx>]

Hi,

I'm trying to build and install GCC 4.7.2, and I'm getting the following
error from the "install-mkheaders" target of gcc/Makefile:

    [...]
    /usr/bin/install -c -m 644 /home/pj/distro/pkg/gcc-4.7/tmp/src/gcc/gsyslimits.h \

            done

I've confirmed that gcc/include-fixed/limits.h is generated when I
build GCC.

I watched for changes to gcc/include-fixed/limits.h while I updated the
"install" target of the top-level makefile:

    $ inotifywait --monitor --format '[%T] %f: %e' --timefmt '%T' gcc/include-fixed/ | grep -F -C 2 limits.h
    Setting up watches.
    Watches established.

    [08:08:45] irrlicht: CLOSE_NOWRITE,CLOSE,ISDIR

The deletion of syslimits.h, movement of limits.h to syslimits.h, and
change to the metadata of syslimits.h all look like the behavior of the
"stmp-fixinc" target.  But as far as I can tell that target isn't being
updated with the top-level "install" target.  (Nor should it be, as far
as I know.)

Does anyone have any idea what's happening here?  Why is
gcc/include-fixed/limits.h being moved when updating the "install"
target?

Let me know if I can provide any other information that may help.

My build system:

  * Linux 3.2.0
  * EGLIBC 2.13
  * GCC 4.7.2
  * Binutils 2.22

Thanks,
