substantial upgrade of newlibc.c occurred. Now the user extension
data area is used rather than notepads and as many routines as possible
were split into other files further reducing the minimum footprint
of an RTEMS executable.

that the per task reentrancy structure was not being processed properly
during exit().

That does the job. cdtest.exe works correctly now.

that added ifdef on the pc386.

with the --disable-posix option, stubs for some routines (_getpid_r and
_kill_r) that are normally defined with POSIX were added.

overhaul of the RTEMS system call interface. This base file system is
the "In-Memory File System" aka IMFS.
The design and implementation was done by the following people:
+ Joel Sherrill (joel@OARcorp.com)
+ Jennifer Averett (jennifer@OARcorp.com)
+ Steve "Mr Mount" Salitasc (salitasc@OARcorp.com)
+ Kerwin Wade (wade@OARcorp.com)
PROBLEMS
========
+ It is VERY likely that merging this will break the UNIX port. This
can/will be fixed.
+ There is likely some reentrancy/mutual exclusion needed.
+ Eventually, there should be a "mini-IMFS" description table to
eliminate links, symlinks, etc to save memory. All you need to
have "classic RTEMS" functionality is technically directories
and device IO. All the rest could be left out to save memory.

I have reworked the ethernet driver for the BSP pc386 and
here is the patch to apply.

the atexit routines on the global reentrancy structure were not
invoked. But it does not seem like a 100% correct solution.

configured.

the inline implementation. The impetus for this was twofold. First,
it is incorrect to have static inline prototypes when using the macro
implementation. Second, this reduced the number of lines in the include
files seen by rtems.h by about 2000 lines.
Next we restricted visibility for the inline routines to inside the
executive itself EXCEPT for a handful of objects. This reduced the
number of include files included by rtems.h by 40 files and reduced
the lines in the include files seen by rtems.h by about 6000 lines.
In total, these reduced the compile time of the entire RTEMS tree by 20%.
This results in about 8 minutes savings on the SparcStation 10 morgana.

Receive Server. As a result, the CPU Table field for extra stack for
the SYSI task was changed to be extra stack for the MPCI Receive Server.

Configuration Table Template file added and all tests
modified to use this. All gvar.h and conftbl.h files
removed from test directories.
Configuration parameter maximum_devices added.
Core semaphore and mutex handlers added and RTEMS API Semaphore
Manager updated to reflect this.
Initialization sequence changed to invoke API specific initialization
routines. Initialization tasks table now owned by RTEMS Tasks Manager.
Added user extension for post-switch.
Utilized user extensions to implement API specific functionality
like signal dispatching.
Added extensions to the System Initialization Thread so that an
API can register a function to be invoked while the system
is being initialized. These are largely equivalent to the
pre-driver and post-driver hooks.
Added the Modules file oar-go32_p5, modified oar-go32, and modified
the file make/custom/go32.cfg to look at an environment varable which
determines what CPU model is being used.
All BSPs updated to reflect named devices and clock driver's IOCTL
used by the Shared Memory Driver. Also merged clock isr into
main file and removed ckisr.c where possible.
Updated spsize to reflect new and moved variables.
Makefiles for the executive source and include files updated to show
break down of files into Core, RTEMS API, and Neither.
Header and inline files installed into subdirectory based on whether
logically in the Core or a part of the RTEMS API.
