gettext 0.17 compilation troubles

[Левашев Иван]

My platform :
Mac OS X 10.4.8
ppc-apple-darwin8.8.1

I wanted to build gettext relocatable (--enable-relocatable) and
install it to some temporary directory (DESTDIR=). Then compiled
gettext is to be copied to a self-contained bundle.

Troubles I had:
configure doesn't detect unsetenv presence. It just doesn't check for
it. Probably gettext needs autoreconf with newer autotools. I've
manually added -DHAVE_UNSETENV to aid compilation (otherwise ld
reports conflicts).

gettext got compiled, but wrappers don't.

Relocation wrapper references void xalloc_die (void)

gettext-runtime/gnulib-lib :

relocwrapper references progreloc, progreloc references xreadlink

And xreadlink calls xalloc_die despite the NO_XMALLOC flag set. grep
-r didn't find any another source file with English-only xalloc_die()
version.
xmalloc can't be used in a wrapper because libintl.dylib can't be
located for a wrapper, it's a wrapper's job to set
DYLD_LIBRARY_PATH.
I first linked libintl statically (for every wrapper), and it worked,
then I've used xalloc_die.c from GNU inetutils/lib:

#include <stdio.h>

void
xalloc_die (void)
{
  fprintf (stderr, "out of memory\n");
  exit (1);
}

That's all. After adding it wrappers get compiled.

Next. Wrappers got compiled, but they don't work because of DESTDIR=

build-aux/install-reloc :

installdir=`echo "$destprog" | sed -e 's,/[^/]*$,,'`

It's wrong when DESTDIR is used.
For example, my destprog is
/Users/OCTAGRAM/Documents/Unix_Build/Dia-app/Intermediate/gettext/out/ppc/bin/gettext

installdir is detected as everything above but "/gettext"

But installdir must be just "/bin" instead.
