Potential issue with numpy

[Andreas Tille <andreas@an3as.eu>]

Hi,

in the issue I filed against nipype I was asked to try to rebuild numpy
and see whether this might make a diffence.  So I tried

  dget http://deb.debian.org/debian/pool/main/n/numpy/numpy_1.19.5-1.dsc
  cd numpy-1.19.5

and have rebuild it in a recent pbuilder environment.  This ends up in

DISTUTILS.rst.txt:386: WARNING: Unparseable C cross-reference: '/**end repeat1**/'
Invalid C declaration: Expected identifier in nested name. [error at 0]
  /**end repeat1**/
  ^

Please also report this if it was a user error, so that a better error message can be provided next time.
A bug report can be filed in the tracker at <https://github.com/sphinx-doc/sphinx/issues>. Thanks!


While I think this could be worth a "does not build from source" bug
against numpy (I'd wait with this until somebody confirms) I wonder
what answer I should give to nipype upstream in the issue[1].

Kind regards

     Andreas.
