RE: Still have build error on 2.6.2 fc/proc/array.c

[yiding_wang]

Hello Marco,

I got things straighten up by changing the code array.c, followed your example on web.  I also downloaded gcc 3.3.3 but dare to try it now. The gcc 2.96 bug should be described in 2.6.2 Changes file which only mentioned the gcc 2.95 and beyond will be OK,

Thanks!

Eddie
