Hi,

I still like this idea a lot.  However, with "make gconfig" I am
seeing a segfault when I click on "Firmware Drivers" in the main menu.
I only see this with these patches applied.

Other than that, they look good to me.

Here's the gconfig info:

Your glibc and gtk version not old, the building environment seems
good, but here I don't have a OpenSUSE 10.3 x86_64, really no idea on
how to resolve that problem, maybe I have chance to install a OpenSUSE
10.3 x86_64 these days, the I will try that,

Today I tested these patches on another pristine debian-5.0 (lenny)
x86_64 system, it also performed well.
On systems I tested (glibc 2.6,2.7,2.8, gtk-2.12 or gtk-2.14), it may
report warnings from gtkitemfactory.h and ununsed variables from
images.c, but doesn't matter, after "scripts/kconfig/gconf
arch/x86/Kconfig" run, the gtk gconfig window will display, with
symbol's value quoted well,

/usr/include/gtk-2.0/gtk/gtkitemfactory.h:47: warning: function
declaration isn’t a prototype

I had already reported that gconfig without this patch series works fine.

With -O0 -ggdb, this is the backtrace:

Hand applied - your patches continue to be wordwrapped.
Please see if you can fix this next time.

[PATCH] scripts/unifdef.c: rename getline symbol to something else

From: Kyle McMartin <kyle <at> redhat.com>

Rawhide builds are currently failing to build unifdef.c, as the next
version of glibc changes the default _POSIX_C_SOURCE level, which
exposes getline() from <stdio.h>

scripts/unifdef.c:209: error: conflicting types for 'getline'
/usr/include/stdio.h:653: note: previous declaration of 'getline' was
here
make[2]: *** [scripts/unifdef] Error 1
make[1]: *** [__headers] Error 2
make: *** [vmlinux] Error 2

Rename the symbol in unifdef.c to parseline to avoid this conflicting
declaration.

Otherwise Jakub says we could add a -D_POSIX_C_SOURCE=200112L as a
workaround to unifdef CFLAGS, but this seems like it would be less
desirable in the long term.

I have a similar patch queued in kbuild-fixes.git.
