>Description:
While trying to compile a i386 -current kernel with 3GB for MAXDSIZ, i'm
getting an error in `sys/kern/kern_resource.c':

#   compile  HAL.BIG/kern_resource.o

/local/src/NetBSD/src/sys/kern/kern_resource.c:62: warning: this decimal constant is unsigned only in ISO C90

For now it passed by making the value unsigned:

options 	MAXDSIZ="3221225472U"

NB: This seems to be a 32bit platform issue as the same value worked
flawlessly on NetBSD/alpha and NetBSD/amd64.

>How-To-Repeat:
compile a kernel, at least on i386, with:
options 	MAXDSIZ=3221225472
>Fix:
