commit 3b78f246db536275db653903a49725179f5945c2
Author: Paul Eggert <address@hidden>
Date:   Sat Mar 3 21:35:29 2012 -0800

    fortran: clean up core files after AC_FC_CHECK_BOUNDS
    
    * lib/autoconf/fortran.m4 (AC_FC_CHECK_BOUNDS): Clean up core
    files, too.  Needed for Sun Fortran 95 8.2 2005/10/13 on Solaris 8.

commit 49b68f063e33f22814de0ce01f4b7119d5c776c3
Author: Paul Eggert <address@hidden>
Date:   Sat Mar 3 21:28:01 2012 -0800

    tests: port AS_TR_SH and AS_TR_CPP test to Solaris 8 wc
    
    * tests/m4sh.at (AS@&address@hidden and AS@&address@hidden): Do not assume
    that "wc -l" outputs only digits; on Solaris 8 it also outputs
    blanks and POSIX allows this.

commit bb454862bb167fb9aeb5222edd5ec1ab974754e1
Author: Paul Eggert <address@hidden>
Date:   Sat Mar 3 18:47:36 2012 -0800

    tests: fix "#/bin/sh" typo
    
    * tests/m4sh.at (AS@&address@hidden): "#!/bin/sh", not "#/bin/sh".
    Typo reported by Tim Rice in:
    http://lists.gnu.org/archive/html/autoconf-patches/2012-03/msg00009.html

commit 7d55ba7fd930ad1f56946ba9d7e9ef573caf93f3
Author: Paul Eggert <address@hidden>
Date:   Sat Mar 3 18:42:21 2012 -0800

    tests: port AS_EXECUTABLE_P test to Solaris 8 /bin/sh
    
    * tests/m4sh.at (AS@&address@hidden): Treat any nonzero exit
    status as failure.  This is needed for Solaris 8 /bin/sh,
    where executing a nonexecutable file causes the shell
    to say the file had exit status 1.
