normally, on an i386 tex the speed of tex does not differ per operating system
(in any case, do a couple of runs to make sure that caching is not playing any role)
the only differences i notice are in terminal output (bitmaps, outlines, kind of
fonts, noflines, etc make a difference)
however, there is one place where speed differs and that is in loading the
pattern files: a djgpp version crawls when loading patterns compared to a native
win32 version; so, it looks like the (cross)compiler has done something wrong
there; could it be that something like that happens on the g4 as well, maybe
something endian or so being messed up?
