Re: [PATCH v2] Overhauled and modularized tests in `instspc.test'.

[Stefano Lattarini]

BRIEF DESCRIPTION
  Run the instspc tests with SunStudio dmake and Solaris /bin/sh, and
  with some GNU tools available.

DETAILS
 * Operating system is Solaris 10 (SunOS 5.10 Generic_141445-09 i86pc)
 * The locale is strictly set to "C".
 * MAKE is forced to dmake (Sun Distributed Make 7.8 SunOS_i386
   Patch 126504-01 2007/07/19)
 * CONFIG_SHELL is forced to the Solaris /bin/sh
 * xpg4, xpg6 and ccs programs are in PATH
 * GNU sed (3.02), GNU expr (from GNU coreutils 6.9), and GNU awk (3.1.5)
   are early in PATH
 * GNU install (from GNU coreutils 6.9) available in PATH as `ginstall'
 * autoconf, autom4te, autoheader and autoupdate version 2.67
 * libtool (GNU libtool) 2.2.10 (should be irrelevant here)
 * the GCC C, C++ and Fortran compilers (version 4.4.4)
 * perl interpreter (v5.12.2)
 * Solaris binutils (as, ld, ar, ranlib, all from /usr/bin/ccs)

OUTCOME
 All the instspc*.test tests behaved as expected.

EXTRA NOTES
 I had to manually tweak Automake's own tests/Makefile.in to revert
 changes introduced in commit v1.11-191-g24e3b4e, which breaks dmake:
