Warner Losh	e8420087b0	Replace memory leaking instances of realloc with non-leaking reallocf. ... In some cases replace if (a == null) a = malloc(x); else a = realloc(a, x); with simple reallocf(a, x). Per ANSI-C, this is guaranteed to be the same thing. I've been running these on my system here w/o ill effects for some time. However, the CTM-express is at part 6 of 34 for the CAM changes, so I've not been able to do a build world with the CAM in the tree with these changes.

Bruce Evans	5dddb8148b	Don't attempt to lstat() the POSIXLY invalid empty pathname. ... realpath() still accepts "" as an arg and converts it to a canonical pathname for the current directory.	1995-02-25 16:06:07 +00:00
