I will implement it if noone does and I have the time. First we
have to agree on what syntax to use. -Bstatic/-Bdynamic or
-static/-dynamic?

Thanks...if you understand how gcc is organized  (I looked at this
in 1.x and saw it was a lot to understand).

This should be trivial...Use -static/-dynamic [does gnu ld understand 
this?]

(its not trivial to even see if ld works this way ;-( )

Doing this is a big win.

-static -lfoo -dynamic -lbar

gcc/gnu getopt liks to reorder options and I cannot use -dynamic
nor -Bxxxxx. You have to use -Wl,-xxxxxx for the time being.

No. Use -Bstatic/-Bdynamic.

Try this one on top of binutils 2.5.2l.11. I have included this
in binutils 2.5.2l.12. You have to use:

# gcc -v foo.o -Wl,-Bstatic -lm -Wl,-Bdynamic 

Please let me know if it works for you. BTW, it may work with
the current snapshot.

-static -lfoo -dynamic -lbar

| No. Use -Bstatic/-Bdynamic.

Except that GCC uses -B for other purposes.

And gcc may reorder flags. That is why I said -Wl,xxxxxx.

BTW, one should not make changes at 2:00am in the morning. I will
make a new simpler patch when I get home today.
