ld --exclude-symbols problems

[Mikhail Kruk]

Hi,
I'm trying to use --exclude-symbols option of ld and it doesn't work.
I have plain unupdated 8.0 system.
I try to run gcc -shared -Xlinker --exclude-symbols -Xlinker blah
or just ld --exclude-symbols blah
and get unrecognized option '--exclude-symbols' error message.
I also tried --output-def with exactly the same result.
Same results on RedHat 7.2 system with ld 2.11.90.0.8. Sorry, don't have 
the exact ld vresion from the 8.0 system, but it's 2.13 something, the 
default one.
Am I doing something wrong? Is it not really implemented? If it is not, 
what is the right way to specify which symbols I want to export from my 
shared library?

Thank you in advance!
