installation problems on Windows 7

Please help me with the following:

I am trying to install FileZilla on Windows 7 from
http://wiki.filezilla-project.org/Compi ... er_Windows .
1. First, since all the instructions are in UNIX file formats, I installed CYGWIN and did mkdir /cygdrive/c/dev.

2. I downloaded all MinGW and MSYS files and extracted them to dev/mingw and dev/msys dirs., correspondingly.

3. Then executed pi.bat. I set up LDFLAGS and CPPFLAGS in .profile, per instructions.

4. Then downloaded libidn, configured make’s and make install’d in /usr/src/compile.

5. Next, downloaded libgpg-error and ran
./configure --disable-shared --enable-static --disable-nls
--prefix=/c/dev/mingw. Then make’d and make install’d.

6. Then downloaded libgcrypt and in libgcrypt-1.4.6 ran
./configure --disable-shared --enable-static --disable-nls
First, I got the warning: WARNING: unrecognized options: --disable-nls
Then in the end,

checking for gpg-error-config... no
checking for GPG Error - version >= 1.4... no
configure: error: libgpg-error is needed.
See ftp://ftp.gnupg.org/gcrypt/libgpg-error/ .

Any suggestions are highly appreciated. Thank you.
