Your subject mentions setup and gio-querymodules; your body mentions 
idn2_punycode_decode, libgnutls30; plus git and git-push.

Please copy and paste the actual commands executed and error messages 
reported, including complete commands for each of the issues involved.
There are German speakers on the list who can clarify for those of us 
who may have issues decoding German tech language.

I would not expect punycode to be anything to do with libgnutls.

I would expect idn2_punycode_decode in cyg/libidn2, but it is not a 
public API symbol for either Cygwin or Windows mingw libraries.

The idn2_punycode_decode issue was a libgnutls/libidn2 compatibility 
problem a couple of years ago but should be fixed now:

Cygwin wget and wget2 are built with libgnutls and libidn2 and have no 
build, test, or usage issues reported.

Have you perhaps an old release of Cygwin installed and have not applied 
any recent upgrades?

Do you perhaps have Git for Windows or some WSL distro installed and in 
your path? Try:

	$ which git; ls /usr/libexec/git-core/git-push

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
