    Don't run system("touch conf.gtktest") in the AM_PATH_GTK_2_0 macro
    
    Just use the C library instead to create the file. Helps building
    using Wine. Not that I think we want to endorse that way to build GTK+
    for Windows, proper cross-compiling surely probably more sense, but
    accepting this minimal patch doesn't hurt. From bug #590017.
