Joel Sherrill b8a30d07a5 Patch rtems-rc-20000713-1-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>
that is yet another multilib-related structual cleanup patch:

  Changes:
  * Make RTEMS_TEST_NO_PAUSE a tests/ subpackage specific option.
    - Remove RTEMS_TEST_NO_PAUSE from custom/*.cfg, targopts.h and
      cpuopts.h.
    - Add autoconf macros RTEMS_*_RTEMS_TEST_NO_PAUSE
      (aclocal/rtems-test-no-pause.m4).
    - Add RTEMS_*_RTEMS_TEST_NO_PAUSE support to sptests/configure.ins
      and tmtests/configure.in. These are the only subdirectories which
      currently apply RTEMS_TEST_NO_PAUSE.
    - Add autoconf-DEFS support to all test subpackages' configure.ins
      below tests/. I.e. AC_DEFINES now get explicitly propagated as
      preprocessor defines into Makefiles, cf. AM_CPPFLAGS in
      tests/*/*.am, instead of using a global config-files.
    - Remove NDEBUG from custom/*.cfg.

  * AC_DEFINE POSIX_API, ITRON_API and MULTIPROCESSING in
    exec/configure.in, only.
    - All other sources now should relay on the values from cpuopts.h
      and should not define them themselves.
    - Several related changes to many configure.ins

  * Bug-fixes to RTEMS_*_RTEMS_DEBUG macros (Actually workarounds to
    quoting bugs in autoconf).

  Notes:
    * This patch is rather immature and only tested for a small subset
      of BSPs (requires the tests to be enabled and therefore takes an
      tremendous amount of disc space and time.)
    * The patches to *cfg were generated by a script. Expect file
      formating changes :)

# CONSOLE_USE_POLLED (erc32_bsp)
# CONSOLE_USE_INTERRUPTS (erc32_bsp)
# The erc32 console driver can operate in either polled or interrupt mode.
# Under the simulator (especially when FAST_UART is defined), polled seems
# to operate better. It is common for a task to print a line (like the
# end of test message) and then exit. In this case, the program returns
# control to the simulator command line before the program has even queued
# the output to the uart. Thus sis has no chance of getting the data out.
#
# SIMSPARC_FAST_IDLE (erc32_bsp)
# If defined, speed up the clock ticks while the idle task is running so
# time spent in the idle task is minimized. This significantly reduces
# the wall time required to execute the RTEMS test suites.
#
# FPU_REVB (erc32_bsp)
# If defined, enables work-around for bug 3.14 in FPU rev.B or rev.C
