Hmmm, I thought I started from a clean slate (I really have no  
choice  - due to disk resource limitations I can only build one of  
{gcc2, egcs} at a time, and I had to build the former to alpha-test  
g77-0.5.23 ...)

I retried `../egcs/configure --prefix=/usr/snp' with a clean object  
directory; this is the relevant part of obj/libiberty/Makefile:

# Warning: this fragment is automatically generated
# Following fragment copied from  
../../egcs/libiberty/config/../../config/mh-m68kpic
PICFLAG=-fpic
enable_shared = yes

which doesn't really surprise me, because IIRC it always built the  
`-fpic' part - the only reason to worry about it this time was the  
invalid assembler produced ;-)

BTW, it seems to take an inordinate amount of time to configure  
libiberty - the first time (before keeping an eye on it with tail -f  
config.log) I thought it hung ...

HTH,
Toon.
