The constant in djlsr204.zip, file src/libc/c99/math/hugevall.c, which 
purports to be an infinity of type long double, is incorrect:

/* Copyright (C) 2003 DJ Delorie, see COPYING.DJ for details */
#include <libc/ieee.h>

long_double_t __dj_huge_vall = { 0x00000000, 0x00000000, 0x7fff, 0x0 };

This constant is actually a denormal and should be:

long_double_t __dj_huge_vall = { 0x00000000, 0x80000000, 0x7fff, 0x0 };

The patch is:
