In -CURRENT it exists in restricted circumstances -- i.e. it only occurs if
you're using a static libc and libc_r, because of the -pg or -static flags
In 5.1-RELEASE it occurs any time you're using libc_r. This was fixed by
mp at FreeBSD.org with a patch on 2003-07-25, but the fix doesn't work for the
static library case. My patch extends mp's fix so it covers the static
library case as well.
