Precisely.
I guess this configuration choice was made because GTK+ cannot use
threading on Windows anyway - so if Lightspark uses GTK+, and calls
its functions (and/or GDK functions) from multiple threads, porting it
will be rather nontrivial. Otherwise (if GLib threading is enough for
Lightspark) you likely will need to configure GLib with
"--with-threads=posix".

Google could have answered this. ;-)
"-mthreads
    Support thread-safe exception handling on Mingw32. Code that
relies on thread-safe exception handling must compile and link all
code with the -mthreads option. When compiling, -mthreads defines
-D_MT; when linking, it links in a special thread helper library
-lmingwthrd which cleans up per thread exception handling data. "
