with the explicit permissions.

Try to bring some sanity to the SCM ID's.
+ spell LIBC_SCCS consistently
+ enable builds with LIBC_SCCS defined to not syntax error
+ minor SCM reformatting to try to have some consistency

Fix the style of the SCM ID's.
I believe have made all of libc .c's as consistent as possible.

This commit was generated by cvs2svn to compensate for changes in r26219,
which included commits to RCS files with non-trunk default branches.

Now the biggest step: import the changes to the main RPC code.

Note: you'll need to rinstalkl all your includes before compiling libc
the next time you update your sources in order for all this to work.
