Yes, and if current GCC has some problems with that, those bugs should
be fixed.  Sorry if I gave the impression that this would be "user  
error".

As long as those scripts are close enough to the "standard" scripts,
it might/should work fine.

In most cases (as far as I have seen) where people use non-standard
linking scripts though, all bets are off (for more or less obvious
reasons), and those people would be much better of calling ld directly.

I only tried to warn the original poster of the perils involved, I  
didn't
try to draw away the attention from the apparent GCC bug.  I guess
I miserably failed, sorry about that :-)
