[svn-r20482] 
Fixed issue HDFFV-5866 (BZ 2156).  Changed scripts to run examples to use specific names for compiled executable files instead of a.out, which did not work on Cywin as it produces a.exe by default.  Removed issue from known problems section of RELEASE.txt.

Tested with Cygwin 1.7.8 on Windows 7.
