Title:
  libm pow() function does not report floating point underflow exception

Status in glibc package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 8.10 for x86-64
  glibc 2.8~20080505-0ubuntu9

  The pow() function in the standard C library does not report a
  floating point underflow exception like it is supposed to.

  Compile the attached program with '-O0 -fno-bultin-pow -lm'. Then run
  it.

  Expected output:

  0.000000
  exceptions:
  	inexact
  	underflow

  Actual output:

  0.000000
  exceptions:
  	inexact
