2.0.7pre4 compile error with libc5-system

[Markus Koelle]

I've compile problems with 2.0.7pre4 on a
libc5-system (SuSE 6.0) .

config.log:

int main() {
; return 0; }
configure:10662: gcc -o conftest -O   conftest.c -ldl  -lcrypt 1>&5
configure: failed program was:
#line 10659 "configure"
#include "confdefs.h"
#include "./tests/summary.c"

With 2.0.7pre2 it works well.

What's going wrong?
