Subject:	Re: Cross Compiling

I think it's even mentioned in some of the configure documentation...
in order to build, for example, an i386(go32) hosted, 68k cross
compiler, we start on a sun4, build sun4 native, then use that to
build sun4-x-i386 and sun4-x-68k, use the sun4-x-i386 to build the
i386-x-68k, and the sun4-x-68k to build the libraries and such... The
scripts are a bit hairy, and it needs more handholding than it
should... but the alternative is actually *using* DOS, and we'd much
rather be able to automate the process.
	GCC is easy to use as a cross compiler. H.J.Lu, who does the
compiler releases for Linux, these days just builds them using a
sun4-x-linux gcc, nothing all that special.

   Cygnus has actually done this, but I don't know how automatic it is.
