If you use Perl's own malloc, makedepend can't find dependencies
for malloc.o in the subdirectories.

makedepend feeds ../malloc.c to stdin of cpp. cpp's algorithm 
used in finding #include "xxx" files depends on the pathname-prefix
of the source file (in Unix implementations).

	/usr/lib/cpp ../malloc.c

finds ../perl.h as include file (as in 4.003 makedepend),  but

	/usr/lib/cpp < ../malloc.c
	
doesn't. (4.010 makedepend)


This causes make to fail in subdirectories, because malloc.o is never
created.
