Some of the post have said I have to build OPENOCD because of licensing limitations. Is this true?
can it be build with cygwin or msys? (I am on a Windows 7 64 dell laptop).

The licensing issues have to do with FTDI’s closed-source .dll to support their chips, e.g. FT2232. There is a open source library that supports these chips, but it is not as fast as the closed-source version. The only (license-related) situation in which you’d need to build your own would be if
a) Your JTAG interface is FTDI-based, and
b) the version of openocd with (open source) libftdi compiled in doesn’t work for you (too slow, or some other reason).
I can’t say from firsthand experience whether Freddie Chopin’s pre-compiled binaries work with 64 bit win7.
