Building _amgio on windows.

[danielenriquez59]

Upfront: I am running a mingw-64 terminal on windows as suggested in the SUAVE build instructions.

From another thread, it was suggested to go into SU2\externals\AMGIO\su2io and try to manually build the _amgio
When I run the command 'python setup.py build_ext -c mingw32' I get the following output.

For anyone following, I got a bit further with the information posted here:
https://github.com/Roche/pyreadstat/blob/master/windows_compilation.md

The next error I got when trying to build was a "getline()" undefined reference.

This is because getline is not a standard C library function and is part of the POSIX package. i.e. the reference does not exist on Mingw/Windows builds. I had to replace all occurrences of getline with fgets. Hope this doesn't break anything in the future.
