bootstrapping gcc trunk on sparc64-linux: warning: comparison of unsigned expression < 0 is always false

[Christian Jönsson]

This was on a Aurora SPARC Linux 0.42 build (Douglas) Ultra1
sun4u system with these packages:

binutils 2.13.90 20030112 sparc64-linux
bison-1.35-1
dejagnu-1.4.3-0	(from ftp://ftp.gnu.org/pub/gnu/dejagnu/dejagnu-1.4.3-0.src.rpm)
expect-5.32.2-67
gcc 3.4 20030112 (experimental) sparc64-linux
glibc-2.2.5-42
glibc64-2.2.5-42
kernel-2.4.19-1.2sparc
tcl-8.3.3-67

In-tree joined gcc and binutils cvs trunks.

The warning: comparison of unsigned expression < 0 is always false is
triggered for these four instances:

gcc/collect2.c:516: warning: comparison of unsigned expression < 0 is always false
gcc/tlink.c:600: warning: comparison of unsigned expression < 0 is always false
gcc/tlink.c:616: warning: comparison of unsigned expression < 0 is always false
gcc/tlink.c:655: warning: comparison of unsigned expression < 0 is always false
