  10 * Here is a slightly simpler and neater test case
  11
  12       program labug3
  13       implicit none
  14
  15 *  This program gives the wrong answer on mips-sgi-irix6.5
  16 *  when compiled with g77 from egcs-19990629 (gcc 2.95 prerelease)
  17 *  Get a = 0.0 when it should be 1.0
  18 *
  19 *  Works with:  -femulate-complex
  20 *               egcs-1.1.2

  22 *  Originally derived from LAPACK 3.0 test suite.
