Another failure:
 _Decimal32 val, lo;
 val = 0.e-40DF;
 lo = 9.e-1DF;
 val += lo;   /* raises FE_INEXACT */

This is with gcc 4.5.1 on Linux Fedora Core 14 on Intel Core 2 in 32-bit mode.

Command line options:
-std=gnu99 -O0 -pedantic -H -fno-builtin -frounding-math -mieee-fp
-ffloat-store -fexcess-precision=standard

This seems like a bug in the library.
