[Bug libstdc++/13284] New: 126 g++ failures due to lrand48 not defined

["giovannibajo at libero dot it" <gcc-bugzilla at gcc dot gnu dot org>]

Hello,

126 out of the 148 failures I see with mainline on cygwin are due to this:

In file included from /home/Administrator/gcc/mainline/out/i686-pc-
cygwin/libstdc++-v3/include/algorithm:69,
                 from /home/Administrator/gcc/mainline/out/i686-pc-
cygwin/libstdc++-v3/include/string:56,
                 
from /home/Administrator/gcc/mainline/gcc/gcc/testsuite/g++.dg/init/array4.C:8: 
/home/Administrator/gcc/mainline/out/i686-pc-cygwin/libstdc++-
v3/include/bits/stl_algo.h: In function `_Distance std::__random_number
(_Distance)':
/home/Administrator/gcc/mainline/out/i686-pc-cygwin/libstdc++-
v3/include/bits/stl_algo.h:1670: error: there are no arguments to `lrand48' 
that depend on a templ
ate parameter, so a declaration of `lrand48' must be available
/home/Administrator/gcc/mainline/out/i686-pc-cygwin/libstdc++-
v3/include/bits/stl_algo.h:1670: error: (if you use `-fpermissive', G++ will 
accept your code, but allowing the use of an undeclared name is deprecated)

Now, newlib does not define lrand48 if __STRICT_ANSI__, and the testsuite is 
run with "-ansi". Danny Smith suggests that cygwin's newlib should always 
define those C99 functions in C++ mode. 

But I wonder, why _GLIBCXX_HAVE_LRAND48 is defined in the first place? 
Shouldn't the configure test for it be run in -ansi mode?
