bug in egcs with C++?

[teunis <teunis at computersupportcentre dot com>]

I'm getting an odd bug in egcs...  (2.92.21 but also .13)
and also .23...

collect2: ld returned 1 exit status

varying -any- of the commandline didn't affect anything - except that I do
use exceptions...

Here's the pertinant code:
("Object" is irrelevant, as is NoSuchElementException.  Tested with both
disabled, no change)
As you can see I'm kinda basing this on Java-1.2 sorta... it's designed to
talk to Java and provide an alternative interface...
Any ideas?

I can provide more info if need be...

Oh.
	linux-2.1.127	(can't downgrade due to requiring fbcon support)
	glibc-2.0.7
	Cyrix 200+, 40MB ram, ~6GB hd space split between 3 drives.

All functions above are defined externally.  If ya want 'em, I'll post
'em, but I don't really think it's a good idea...

I have not yet worked out any other conditions that cause this.

G'day, eh? :)
