Post failed: Couldn't connect to host

[pinggit]

whenever I do:
:Gist

I was asked to input github password, after I did it, then I got these:

Posting it to gist...433659858
Posting it to gist...
Post failed: Couldn't connect to host
Press ENTER or type command to continue

pity that it never worked for me ...

Maybe, your environment doesn't accept your to access https://api.github.com/

[pinggit]

it looks curl does not work in cygwin64

C:/data/cygwin64/bin/curl.exe: error while loading shared libraries: cygmetalink-3.dll: cannot open shared object file: No such file or directory

it works fine with cygwin32. I think it is not gist-vim issue. will close it.
thanks!

any idea how to make curl work with cygwin64 ? :p
