Title:     I am trying to build a cross-compiler for the SC100 family. I have a directory (config/quartz) containing the following files:         quartz.c         quartz.h         quartz.h.coff         quartz.h.physical         quartz.h.virtual         quartz.md         quartz.md.bak         quartz.md.exp1         quartz.md.exp2         quartz.md.exp3         quartz.md.exp4         quartz.md.v49    I know what quartz.c , quartz.h , quartz.md are used for. I suppose that quartz.md.bak is a backup file and that the other .md files are simply different versions. I don't know what should I do with quartz.h.coff ,   quartz.h.physical and   quartz.h.virtual .    I tryied to compile using configure --target=quartz-local and I almost did it, but it doesn'n sound right. I think I should use a different option for configure, but I can't figure out  which one.     Something I should have said from the very beginning : I work on SunOS5.7, installed on a i386 machine.     Please write me if you can help.                       Virgil.   Â
