[Description Chen Xiangyang 2005-06-04 04:17:54 UTC]

1. archieval/gzip.c: declaration as 'static int' but implementation as 'static
const int'
2. networking/ifupdown.c: 'static char ** environ' conflicts with stddef.h

Reproducible: Always
Steps to Reproduce:
1.untar 
2.'make', when config, check 'Network Utilites->ifupdown'
3.'make' again

Actual Results:

-Os -march=i386 -mpreferred-stack-boundary=2 -falign-functions=0 -falign-jumps=0
