fntest.m results in test directry on cygwin octave : check rand.cc

[Tatsuro MATSUOKA]

Hello

I have not carried out make check on the cygwin because run_octave did not work.
Today I have found the test directory in the extracted source file directories 
and carried out the
'fntests'. 

********************************
Summary:

  PASS   2617
  FAIL      2

There was 1 expected failure (see fntests.log for details).

Expected failures are known bugs. Please help improve
Octave by contributing fixes for them.

1514 (of 1667) files have no tests.  Please help improve Octave by
contributing tests for these files (see the list in the file fntests.log).

I checked the fntests.log.

So I have carried out.

I think this difference is trivial and perhaps comes from the implementation of 
rand() function on
cygwin gcc is different from the gcc on other platforms.

Is this right? Can I ignore the difference?
