Thanks. I have that already though. Does your build remake the
crt0 crtbegin and crtend routines in lib/csu and then rebuild the
libraries, and follow up by relinking all the programs? 

If not, I may have something weird here that i need to fix. It seems
to me that after doing a make build, a second make build should just
scan through the tree and not build anything over again, as it is all
up to date. (assuming UPDATE=1 so you don't have a make clean done on you)

This is assuming that for some reason the above mentioned .o files are
not rebuilt each time for a specific reason that I don't know of.
Possibly version info?

One other concern that I had, which upon further thought is not that big
of a deal, is that if you are using a separate obj directory for the 
results, any deletions in the sup will not be reflected in the obj tree.
However, I assume that although there are pieces left hanging in the obj
tree, the make files will not try to install that stuff so it is just
taking up space, and not able to trash anything out by being out of date.
