The __attribute__ extension may not be supported. Certainly the case with
an older UNIX system like Solaris 8 and a compiler such as Sun ONE Studio 11
which is the last compiler from Sun supported on Solaris 8.
the error that I see :

My quick hack, not very elegant patch :
$ diff lib/verror.h.backup lib/verror.h
26a27,38
#ifndef __GNUC__
/* this is not the GNU GCC compiler
* therefore __attribute__ may not work */
#define __attribute__(x)
#endif
#ifdef __SUNPRO_C
/* this is a Sun or Oracle Studio or Forte compiler
* and __attribute__ may not work */
#define __attribute__(x)
#endif
This works fine and :
$ gmake check
.
