i checked over here and it looks fine to me. can you attach your config.log ?
also, try running it through strace and see what it looks like. something like:
$ strace -e '!read' grep ...
you should see calls like:
openat(AT_FDCWD, "...", O_RDONLY|O_NOCTTY|O_LARGEFILE) = 3
fstat64(3, {st_mode=S_IFREG|0644, st_size=8539650048, ...}) = 0
