[Bug-cpio] cpio 2.6 patch for freebsd 5

[Christian Recktenwald]

two bugs on compiling cpio 2.6 for freebsd 5.4:
- function "isnumber" in src/userspec.c is a libc function
        NAME
                 isdigit, isnumber -- decimal-digit character test

        LIBRARY
                 Standard C Library (libc, -lc)

        SYNOPSIS
                 #include <ctype.h>

                 int
                 isdigit(int c);

                 int
                 isnumber(int c);

        DESCRIPTION
                 The isdigit() function tests for a decimal digit character.  
Regardless
                 of locale, this includes the following characters only:

                 ``0''         ``1''         ``2''         ``3''         ``4''
                 ``5''         ``6''         ``7''         ``8''         ``9''

                 The isnumber() function behaves similarly to isdigit(), but 
may recognize
                 additional characters, depending on the current locale setting.

  replaced with "isnumberstring"

- "alloca" in src/userspec.c and src/makepath.c may not become overridden
  with __builtin_alloca because it's defined inside alloca.h

  added #ifdef __FreeBSD__ ...
