Patch installed for 3.3 warnings

["Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>]

These warnings have already been cured on the trunk.  So I pulled the
patches to fix them from the trunk over to the 3.3 branch.

 > calls.c:2086: warning: function declaration isn't a prototype
 > loop.c:3280: warning: comparison between signed and unsigned
 > cp/decl2.c:703: warning: `fndecl' might be used uninitialized in this function
 > java/jcf-io.c:383: warning: passing arg 3 of `scandir' from incompatible pointer type
 > java/jcf-write.c:1784: warning: comparison between signed and unsigned


Bootstrapped on sparc-sun-solaris2.7 and installed as "obvious".


2003-01-24  Kaveh R. Ghazi  <ghazi@caip.rutgers.edu>

	* calls.c (fix_unsafe_tree): Prototype.
	* loop.c (loop_invariant_p): Avoid signed/unsigned warning.

cp:
	* decl2.c (check_classfn): Fix uninitialized warning.

java:
	* jcf-io.c (caching_stat): Cast the 3rd arg of scandir to void*.
	* jcf-write.c (generate_bytecode_insns): Avoid signed/unsigned
	warning.
