Hello to everyone,
yesterday I've uploaded a new cmus package, with some optional
features enabled.
Today, through setup.exe, I noticed that now cmus brings clang as
dependency.
Is there something I can use for analyzing transitive dependencies of
a package?
It does not make sense for an audio player to bring a compiler as
dependency, and would like to remove the offending dependency.
Try the cygcheck-dep tool, downloadable through setup.exe. It was
created to answer questions just like this. Recommended :-).

Thank you, very useful.
Still some questions, as I might be me holding it wrong.
First; is it expected that I need admin rights to execute it?
----
mkdir: cannot create directory ‘/var/cache/cygcheck-dep’: Permission denied
/usr/bin/cygcheck-dep: unable to create cache directory:
/usr/bin/cygcheck-dep: /var/cache/cygcheck-dep
----
Can't it use /tmp or some other location for caching data?
After my first run as admin, after 2 minutes, I got following output
----
cygcheck-dep -r cmus
bzip2: /var/cache/cygcheck-dep/cygwin/x86_64/setup.bz2: data integrity
(CRC) error in data
You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.
/usr/bin/cygcheck-dep: failed to check integrity of downloaded
<setup.ini> file:
/usr/bin/cygcheck-dep: /var/cache/cygcheck-dep/cygwin/x86_64/setup.bz2
/usr/bin/cygcheck-dep: you may try to run with -c option to use cached
file from previous download
----
Might have been a spurious error, because after a rerun (without -c) I
did not get that error anymore.
Third run; are all those warnings expected?

cmus: recursively requires ( ... a lot of packages ... )
----
otherwise, the ouput of "recursively requires" was helpful, but only
limited; I could see clang as dependency, but not why.
I used "cygcheck-dep -n clang" and followed the dependency chain
manually; I hoped that "cygcheck-dep -R cmus" would have showed
something like a tree structure.
But here comes the important question.
How can I use cygcheck-dep for a package that has not been uploaded yet?
I would like to avoid uploading a new package, and verify afterwards if
everything looks fine or not.
