5e34bf4b95 Added "sigemptyset()" call to insure that the memcmp() would work. 
It appears that the new glibc does not clear all the bits of the signal
set with a sigprocmask.

e63e254e4c Corrected bug per Katsutoshi Shibuya's report: 
The definition of "BEGIN_DATA" should not be null; should be ".data".
    Also, the definition of "BEGIN_BSS" should be ".bss".  For this error,
    the compiled object has codes that write on the text segment area.
    It is fatal when the code runs on ROM.

0a6fb223b6 Patch from Chris John <cjohns@awa.com.au> to add use of a select statement 
in the unix port idle thread task.  This should keep the entire application
from blocking when any component does a blocking application.  Also added
TOD_MICROSECONDS_TO_TICKS.

77d20fb28d Replaced warning message for cpus which do not have hardware support 
for an interrupt stack.  Hopefully this will encourage someone to
implement software stack switching on the m68k.

254b445071 This set of changes is the build of what was required to convert to 
GNU autoconf.  This is the first large step in allowing an RTEMS
user to perform a one-tree build (per crossgcc FAQ) including RTEMS
in the build process.  With this change RTEMS is configured in
built in the same style as the GNU tools, yet retains the basic
structure of its traditional Makefiles (ala Tony Bennett).
Jiri Gaisler (jgais@wd.estec.esa.nl) deserves (and received)
a big thank you for doing this.

There are still issues to be resolved but as of this commit, all target
which can be built on a linux host have been using a modified version
of the source Jiri submitted.  This source was merged and most targets
built in the tree before this commit.

There are some issues which remain to be resolved but they are primarily
related to host OS dependencies, script issues, the use of gawk
for hack_specs, and the dependence on gcc snapshots.  These will
be resolved.

d196e48590 updates from Tony Bennett.
