I think this is the known problem with GNU libc having a weird
(non-SUS-spec) strerror_r.  There's a workaround in the 8.0 sources
but it doesn't look like anyone's backported it to 7.4.  You can
drop the pqStrerror() code from CVS tip src/port/thread.c into 7.4
if you like (this will not work in general because 7.4 configure doesn't
set STRERROR_R_INT, but it should work for the case you want).
