I found too many problems related with having some packages ~x86 and
some x86, and in general my experience with ACCEPT_KEYWORDS="~x86"
has been a really pleasant one (I mean, I've been using gentoo for years now,
and ~x86 is alot more stable now than it was before).
I tried reverting to gcc-4.1.2 and recompiling gnustep-base but it didn't
change anything, I can try reverting glibc as well, but I'd rather try other
things first if possible.

I've tried this already, but the debug flags are being stripped so far
as I can tell. Take
a look at the example below which I randomly selected from the
compilation output :

i686-pc-linux-gnu-gcc NSIndexPath.m -c \
              -MMD -MP -DGNUSTEP_TARGET_DIR=\".\"
-DGNUSTEP_TARGET_CPU=\"ix86\" -DGNUSTEP_TARGET_OS=\"linux-gnu\"
-DGNUSTEP_IS_FLATTENED=\"yes\" -DLIBRARY_COMBO=\"gnu-gnu-gnu\" -Wall
-Wcast-align -DGNUSTEP -DGNUSTEP_BASE_LIBRARY=1 -DGNU_GUI_LIBRARY=1
-DGNU_RUNTIME=1 -DGNUSTEP_BASE_LIBRARY=1 -D_REENTRANT -fPIC -g -Wall
-DDEBUG -fno-omit-frame-pointer -DGSWARN -DGSDIAGNOSE -Wno-import
-march=prescott -pipe -fno-strict-aliasing -fexceptions
-fobjc-exceptions -D_NATIVE_OBJC_EXCEPTIONS -fgnu-runtime
-fconstant-string-class=NSConstantString -I../Headers/Additions
-I../Headers -I./. -I. -I/usr/GNUstep/System/Library/Headers
-I/usr/GNUstep/System/Library/Headers -I/usr/include/libxml2
-I/usr/include -I/var/tmp/portage/gnustep-base/gnustep-base-1.14.0/temp/GNUstep/Library/Headers
-I/usr/GNUstep/Local/Library/Headers
-I/usr/GNUstep/System/Library/Headers \
               -o obj/NSIndexPath.o

This is with -ggdb on the CFLAGS, splitdebug on FEATURES and debug on
gnustep-base's
USEflags. Am I doing anything wrong ?

Ok, there are lots of USE flags there that are related to a bug on
gtkphoto2 which
I still haven't had the time to take a better look at (I've got a
canon camera, but the
canon useflag is not adding support for it, so I brute forced and set
all useflags
possible). I can cut down my USEflags, but that would involve rebuilding the
entire system, and I would really prefer another solution to finding
out what's wrong
if possible.
I mean, my idea with building gnustep is basically to test Étoilé for some time.
