Decimal floating point requires <fenv.h>.  The DPD code only requires the 
header, not any of the actual functions it declares; it looks like the BID 
code requires the functions (which uClibc does provide on x86, though not 
on most targets).  So either configure uClibc with UCLIBC_HAS_FENV 
enabled, or configure GCC with --disable-decimal-float.
