broken installation, some dll's are missing.

try "cygcheck g++"

Found: E:\cygwin64\bin\g++.exe
E:\cygwin64\bin\g++.exe
   E:\cygwin64\bin\cygwin1.dll
     C:\Windows\system32\KERNEL32.dll
[cut]
   E:\cygwin64\bin\cygiconv-2.dll
   E:\cygwin64\bin\cygintl-8.dll

"Run cygcheck -s -v -r > cygcheck.out and include that file as an 
attachment in your report. Please do not compress or otherwise encode 
the output. Just attach it as a straight text file so that it can be 
easily viewed. "
