build fails due to 'lib/assert.h' on mac os x

[Assaf Gordon]

Hello,

Trying the latest coreutils (including the update to recent gnulib 7da1068a87c),
I get the following build error on Mac OS-X:

 $ git clone git://git.sv.gnu.org/coreutils.git
 $ cd coreutils/
 $ git id
 v8.25-66-gd47090d
 $ (cd gnulib ; git id )
 v0.1-865-g7da1068

 $ ./bootstrap 
 $ ./configure 
 $ make
 [...]
    GEN      man/whoami.1
    GEN      man/yes.1
    GEN      lib/charset.alias
    GEN      lib/ref-add.sed
    GEN      lib/ref-del.sed
  Making all in gnulib-tests
  make[2]: *** No rule to make target `lib/assert.h', needed by `all'.  Stop.
  make[1]: *** [all-recursive] Error 1
  make: *** [all] Error 2

The versions are:
 $ uname -sr
 Darwin 14.4.0
 $ autoconf --version | head -n1
 autoconf (GNU Autoconf) 2.69
 $ automake --version | head -n1                                                
 
 automake (GNU automake) 1.15
 $ gcc -v

Build does not fail on Debian 8.4 with:
  $ gcc --version | head -n1
  gcc (Debian 4.9.2-10) 4.9.2
  $ autoconf --version | head -n1
  autoconf (GNU Autoconf) 2.69
  $ automake --version | head -n1
  automake (GNU automake) 1.14.1


I'll be able to investigate further tomorrow.
