Thank you, Barry. I tried the file c++/compilers/cygwin/ but 
failed. I wrote to the help desk of NCBI Blast+. They have no guidelines 
for Cygwin users and also suggested the windows version. Actually, I am 
using the windows version now. The only shortcoming is that the windows 
binaries do not recognize the linux-like Cygwin path, so the soft links 
to the blast databases become invalid. I have to change to the directory 
of the Blast database every time I want to run blast search. Anyway, it 
works although a bit inconvenient. Thanks again for your help.
