 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
 to gcc.
 
 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.
