create_xml_reporter() crashes on MSYS platform about cgreen

[tpecar]

To be more specific, it crashes while running the test, so within the run_test_suite() call, but this is due to failing to open a tmpfile in create_xml_reporter()

I can't reproduce this under MSYS2/NT, but the example does crash under MSYS2/MinGW (both 32 and 64). Which one were you running?

We do not have an official list of supported platforms it seems, but I know I at some point struggled with the MSYS2:s and could not figure out how to make Cgreen work on the MinGW-versions. AFAIK the MSYS2/NT is Cygwin-based, which is a "Unix Emulation", which makes it more straight forward to compile *nix programs on a Windows box.

I'm not familiar enough with the MinGW environment to understand why tmpfile() would fail and what to do then. (Sure an error message would be slightly better than a crash, but it would not make Cgreen run on MinGW...).
