This is a patch to rsync 2.5.5, and it serves two purposes. The small
patches to batch.c, flist.c and log.c simply add "void" to some function
definitions so that all declarations in proto.h have full parameter lists.

	unsigned char read_batch_flags()	OLD
	unsigned char read_batch_flags(void)	NEW

The SCO UNIXWare compiler correctly objected to these functions not
having a prototype in scope. The fix seems to be innocuous and should
not break anything. It does seem to require a "make proto" afterwards
to rebuild proto.h

The change in popt/popt.c is to work around a bug in the SCO UNIXWare 8
compiler: it doesn't properly deal with alloca() being called from the
middle of another function call. The code dumps badly on this platform
with all modes (debug, regular, optimized), and the workaround shown
gets around the bug and likely obviates similar bugs on other platforms.
