There is problem building on mingw in with it cannot generate the Glib-2.0 GIR file. The problem comes from make file when it's in 

INTROSPECTION_SCANNER = \
    env PATH=.libs:$(PATH) \
        LPATH=.libs \
        PYTHONPATH=$(top_builddir):$(top_srcdir) \
        UNINSTALLED_INTROSPECTION_SRCDIR=$(top_srcdir) \
        UNINSTALLED_INTROSPECTION_BUILDDIR=$(top_builddir) \
        $(top_builddir)/g-ir-scanner

The thing is on windows there is a $PATH env variable has C:\Program Files\ and when this line of code calls for $(PATH) it breaks with no such files or directory because the space between Program and Files. So all introspection object have the same problem when building, the only way to suppress is by using --enable-introspection=no. But the thing is that I need introspection in this case.
