[Bug c/27899] New: Compile warning with --combine and global register variables.

[dwmw2 at infradead dot org]

$ echo 'register struct foo *current asm ("r2");' > foobar.c
$ gcc --combine foobar.c foobar.c -c 
foobar.c:1: warning: register used for two global register variables


Is this warning harmless? It's still going to do the right thing, yes?

Also happens on i386 (with s/r2/ebx/)
gcc version 4.1.1 20060525 (Red Hat 4.1.1-1)
