That's glibc using __block as a variable name where clang treats it as a
storage specifier. Here's the workaround that Quentin came up with for
the same issue in gnustep-base:

#ifdef HAVE_UNISTD_H
#ifdef __block
/* Turn off Clang built-in __block */
#undef __block
#endif
#define __block __gs_unistd_block
#include <unistd.h>
#undef __block
#endif

Hmm. That odd. For me `PREFIX=/tmp/test make install' installs libobjc2
into /tmp/test.
