Fixed a couple of nitpick warnings, plus one that slipped through the
net earlier.
This directory now compiles without any warnings with -Wall! (Until
the next gcc upgrade...)
1. Added missing function prototypes.
2. Added missing function return types.
3. Added missing function argument types.
4. Added missing headers for system function prototypes.
5. Corrected format specifier in printf().
6. Added extra parentheses around assignment used as truth value.
7. Added missing "default" cases in switch statements.
8. Added casts for function pointers.
9. Did *not* change int declarations of uid and gid to uid_t/gid_t
because I don't know if that would affect the protocol. Put in
explicit casts to int instead, to make things more obvious.
10. Moved declarations of variables that are only used if YP is
defined inside the '#ifdef YP' conditionals.
but a commit mail got lost, it's the same as for this commit:

lib/libc/regex engine.c regcomp.c regerror.c
Minor cleanup, mostly unused vars and missing #includes.
Limit the number of quad functions we pull in for 'i386'.
I still belive the quad stuff should go back into gcc.
Add compile-time warnings about crypt functions.
