GCC can't parse this as C++ code:

extern long double _Complex cacosl (long double _Complex __z) __asm__ ("" "=
cacos") throw ();

complex.cc:1: error: expected initializer before =E2=80=98throw=E2=80=99

This breaks configuring libstdc++, when it tries to find out whether
<complex.h> is C99 complatible.

__REDIRECT_NTH takes care of that.

Andreas.

	* math/complex.h [__LDBL_COMPAT]: Use __REDIRECT_NTH.
