compiling GRASS GIS in Cygwin and Windows 10

[Massi Alvioli <nocharge at gmail dot com>]

Hi all,

I need a bit of help with GRASS GIS compiled with cygwin and Windows
10. Right after a Cygwin update,
a few weeks ago, my GRASS 7.2 gui stopped working with a cryptical
Cygwin-related error message reported below.
I tried rolling back a few wxPython-related Cygwin packages to
previous versions, but I had no luck. I also run rebase
a few times, as suggested to heal similar problems in some web
location. Same result going to grass74 (to which the
errors above refer). The source package is here:
https://grass.osgeo.org/grass74/source/grass-7.4.0.tar.gz
and the list of options used to compile GRASS and a cygcheck dump are
attached here!
