W32: no way to see std output of non-console programs
@ruslanizhb
Submitted by LRN Link to original bug (#790857)
Description
GTK4 uses meson, which links all GUI apps with -mwindows by default, which makes them run without attaching to a console and without having any std streams. All g_log*() functions invoke the default std stream writer, which fails, because std streams are absent. Thus the program has no visible output, which greatly impedes the process of debugging it.
