egcs refuses to link when not optimizing, on DEC Unix 3.x

[Hugues Talbot <Hugues dot Talbot at cmis dot CSIRO dot AU>]

	Hello all, 

	This is on a DEC alphaStation 200 4/233 running DU 3.2

	I'm encountering a puzzling problem with egcs versions
1.02 and 1.03a (exact same problem, apparently). When compiling
a largish C++ application with debugging enabled (-g), if 
I turn the optimizer on (-02), the compiling and linking goes
alright.
	If I **DON'T*** turn the optimizer on at all (just -g),
the program refuses to link with the following errors:

c++ -DOSF1 -O2 -g -Wall -o imview imview.o menubar.o imageViewer.o imageIO.o 
my_Image.o imdebug.o readgif.o readtiff.o readZimage.o imtranslate.o 
readjpeg.o pointfile.o keyboard.o menucb.o readics.o imlines.o imDrawPoint.o 
printPrefs.o savePrefs.o imageInfo.o transferFunction.o transferBox.o 
transferHistoBox.o transferFunctionBox.o fluid/imview_ui.a io/imview_io.a  
- -lfltk_db -lGL -lX11  -lm -ljpeg -ltiff

	This program compiles, links and runs fine with g++-2.7.2.2 on the
same platform. I don't know what it does with egcs on other platforms.

	Any idea what might be going on? I've had a very quick look through
the archive, Apologies if this problem is well-known.

	Please respond by e-mail as I don't subscribe to the 
mailing list. Let me know if you need more details.

	Cheers.
