v1.12.README
I froze this version in anticipation of the linux port.  The major new feature
in v1.12 is the exec server architecture and implementation, along with bug fixes,
etc.  The rpc package is now incorporated in pcr, but it still references the 
sun libraries.

To avoid starting an exec server process, invoke ppcr with the -noexec option.  Otherwise
an exec server is started and the "sys" command is registered for executing (Bourne) shell
commands from the pcr: command prompt.

v1.11.README
I froze this version in anticipation of starting removal of the Spawn code.  
Before the freeze I:
	incorporated the rpc subdirectory from v1.9-4.1.3, making enough changes to
	get it to compile successfully in both the SOLARIS and SUNOS configurations.
	It does not link successfully: missing libraries in the ld command of the 
        top level makefile are the suspected cause.  (n.b. the rpc directory refers to
	thread-unsafe Sun libraries.  It still needs to have PPCR native implementations of
	things like gethostname, gethostbyname, etc.)

	modified the makefiles for the gc component.  make depend now works for gc in the same
	way as for all the other components.  I also had to tweak the gc Makefile to remove
	pcr-specific files in the clean: target.
