Bug 79637

Description of problem:

Hello there,

I just tried to compile package grub-0.92-7 from Redhat 8.0.

Here are some of the compiler messages.

fsys_ext2fs.c:494: warning: `str_chk' might be used uninitialized in this function
fsys_minix.c:303: warning: `str_chk' might be used uninitialized in this function
fsys_reiserfs.c:761: warning: operation on `depth' may be undefined

Here is an untested patch which shuts up the compiler.
