The patch made by Michael is effective when round function is not detected in the ./confugure.
For mingw case, the round fuction flag is true so that his patch is not effective.
This problem caused by bug of mingw gcc complier and it seems fixed the latest complier, gcc 4.30 on
mingw.

To use Michael's round fucntion, I always modify the config.h after configure.

/* Define to 1 if you have the `round' function. */
* #define HAVE_ROUND 1*
  |
  V
/* Define to 1 if you have the `round' function. */
/* #undef HAVE_ROUND */

Then test will be successful.
