I tryed find that _FPU_SETCW function where is declared on alpha but find none 
specific for alpha CPU except 
a very generic declaration in sysdeps/generic/fpu_control.h where it declares 
_FPU_SETCW is null.

I have no idea what _FPU_SETCW must to do and find none tricks to make it build 
up for alpha.

I used to compile CVS version is glibc-2.3.2-51 RH rawhide (with posix patch 
aplied for make xstatconv.c compile).
