well, i took a quick look at bidi_resolve_neutral() (from the stack above) , 
and this
block doesnt really look nice. needs some more parenthesis i think.

 if (!(type == STRONG_R
	|| type == STRONG_L
	|| type == WEAK_BN
	|| type == WEAK_EN
	|| type == WEAK_AN
	|| type == NEUTRAL_B
	|| type == NEUTRAL_S
	|| type == NEUTRAL_WS
	|| type == NEUTRAL_ON))
   abort ();

make it

 if (!((type == STRONG_R)
	|| (type == STRONG_L)
	|| (type == WEAK_BN)
	|| (type == WEAK_EN)
	|| (type == WEAK_AN)
	|| (type == NEUTRAL_B)
	|| (type == NEUTRAL_S)
	|| (type == NEUTRAL_WS)
	|| (type == NEUTRAL_ON)))
   abort ();

i did have some unexplicable problems because of parenthesis
sometimes...

if i could compile it i could help, but i cant :(

anyway, i tried  ./configure then make.  "make" gives this error.

[root at localhost emacs]# make
Your tree does not include the compiled Lisp files.
You need to do `make bootstrap' to build Emacs.
Emacs now requires Texinfo version 4.2.
make: *** [maybe_bootstrap] Error 1
[root at localhost emacs]#

and "make bootstrap" gives a big 27 MB file in /src and this error

Finding pointers to doc strings...
Finding pointers to doc strings...done
Dumping under names emacs and emacs-22.0.0
make[1]: *** [bootstrap-emacs] Segmentation fault
make[1]: Leaving directory `/root/em/emacs/src'
make: *** [bootstrap] Error 2
[root at localhost emacs]#

i wanted to help, but couldnt get the thing compiled, any hints ?
