Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:

    Yet some more modifications, I would recommend to be considered before
    releasing a snapshot:

    1. Cleanup to aclocal/
    cvs rm -f aclocal/cygwin.m4
    cvs rm -f aclocal/exeext.m4

    They are neither used nor needed anymore, however they also don't
    disturb (we use autoconf-2.13's AC_EXEEXT instead, now)

    ----------

    2. rtems-rc-19990328-0.diff
    Some (minor) bug-fixes:
    * make/Templates/Makefile.inc.in: use the new installation directory
    ($(prefix)/ instead of $(prefix)/rtems/)
    * c/src/exec/score/tools/generic/Makefile.am: added line to include local.am
    * c/src/exec/score/tools/*/configure.in: added CVS Id header

    ----------

    3. rtems-rc-19990328-1.diff
    Enhancements and cleanups to autogen, rtems-polish.sh, configure.in etc.

    * autogen: Use the file "VERSION" to detect RTEMS toplevel directory,
    extended usage-message, use "find -print"
    * c/update-tools/cipolish: New script to beautify configure.in scripts
    * c/update-tools/rtems-polish.sh: Use the file "VERSION" to detect RTEMS
    toplevel directory, extended usage-message, added variable for perl
    scripts' subdirectory, use "find -print", cipolish support, new options
    -ac -am -ci.
    * aclocal/*.m4, configure.in: moved some AC_SUBST lines to aclocal/*.m4
    (reduces size of configure.in
    scripts, eases splitting configure.in scripts).
