>Description:
If one passes -Wl,-oldstyle_liblookup to gcc
(in order to pass the option to ld),
collect2 interprets the option as specifying the 
output file.

i.e. "-ofoo" is the same as "-o foo"

In the latest snapshot, SWITCHES_NEED_SPACES can be defined
to prevent this problem,
>How-To-Repeat:
gcc -o foo -Wl,-oldstyle_liblookup foo.c
>Fix:
For 2.95 - without some recoding, nothing can be done,
for newer gcc's, define SWITCHES_NEED_SPACES "o" in
gcc/config/alpha/osf.h
