CURRENT buildworld woes

[José de Paula Rodrigues]

Greetings all,

I have an annoying problem when trying to build world: make depend
complains about not finding a certain unwind.h, when compiling
libstdc++.

My CC in make.conf is set to gcc, my CXX is set to g++, CFLAGS and
CXXFLAGS are both empty (both in make.conf and in my environment). It
doesn't matter whether I do a make clean or not, if I rm -fr /usr/obj
or not, I'm always getting this error, no matter what.

uname -a:
FreeBSD luna.pinguim 6.0-CURRENT FreeBSD 6.0-CURRENT #3: Sat Jun  4

i386

command issued:
make buildworld KERNCONF=LUNA

last few lines of output:

This is it; if you want, I have the complete log for the buildworld,
won't post it here because it is 1.8 MB.

Oh, by the way, unwind.h IS there, in /usr/src/contrib/gcc/unwind.h.

Anyone with this problem? Any known fix/workaround?
