Are binutils and gcc's include/hashtab.h supposed to be in sync?

[Christian Jönsson <christian at j-son dot org>]

I am building, from time to time, the gcc and binutils cvs sources at
the same time. I have a directory where the sources both reside,
/usr/local/src/gcc-binutils/trunk, i.e., the binutils cvs trunk source
tree (top src) and gccc cvs trunk source tree (top gcc) are in that
dir.

Now, to jointly build the sources, I created a directory
/usr/local/src/gcc-binutils/trunk/gcc-binutils and in that dir, I
first created an include subdir. Then, I made symbolic links

chj@fw:/usr/local/src/gcc-binutils/branch$ mkdir gcc-binutils
chj@fw:/usr/local/src/gcc-binutils/branch$ cd gcc-binutils
chj@fw:/usr/local/src/gcc-binutils/branch/gcc-binutils$ mkdir include
chj@fw:/usr/local/src/gcc-binutils/branch/gcc-binutils$ ln -s ../gcc/* .
ln: `./include': cannot overwrite directory

Now, building the joint sources gave me a hint... things aren't perhaps too good here...

gcc-3.2 -W -Wall -Wstrict-prototypes -Wmissing-prototypes -g -o .libs/size size.o bucomm.o version.o filemode.o  ../bfd/.libs/libbfd.so -L/usr/local/src/gcc-binutils/branch/objdir/libiberty/pic -liberty ../libiberty/libiberty.a -Wl,--rpath -Wl,/usr/local/gcc-binutils/32/lib
bucomm.o(.text+0x64c): In function `make_tempname':
/usr/local/src/gcc-binutils/branch/gcc-binutils/binutils/bucomm.c:238: the use of `mktemp' is dangerous, better use `mkstemp'
../bfd/.libs/libbfd.so: undefined reference to `htab_create_alloc'
collect2: ld returned 1 exit status
make[3]: *** [size] Error 1
make[3]: Leaving directory `/exports/gcc-binutils/branch/objdir/binutils'
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory `/exports/gcc-binutils/branch/objdir/binutils'
make[1]: *** [all-recursive-am] Error 2
make[1]: Leaving directory `/exports/gcc-binutils/branch/objdir/binutils'
make: *** [all-binutils] Error 2

So, I started to look again... It comes out that the hashtab.h in
binutils cvs is not in sync with gcc's one...

hmm, am I perhaps doing the joining of the sources in a wrong way?

is it perhaps just so that this specific file happened to be out of
sync?
