This looks like it is the problem, yes.
Texinfo/ModulePath.pm is meant to reside in build/tp/.
The line texi2any.pl:84 is meant to add this directory to @INC.
We can see that it the value that it adds is
\cygdrive\d\a\ci-check\ci-check\texinfo-7.1.0.91-20240901\build\tp
but since this is a native Windows perl, it should really be
D:\a\ci-check\ci-check\texinfo-7.1.0.91-20240901\build\tp
(with slashes or backslahes, doesn't matter).
This value comes from texi2any.pl:65..66:
($real_command_name, $command_directory, $command_suffix)
= fileparse($0, '.pl');
But $0 should be "../../../tp/texi2any.pl", a relative file name.
And an experiment shows that in this case, $command_directory should
be "../../../tp/" (cf. the experiment that I did in
https://github.com/gnu-gnulib/ci-scratch/actions/runs/10671347822 ).
So, like you, I don't understand where this Cygwin-syntax filename
comes from.
