Function symbols with size 0

[Bharadwaj Yadavalli]

I notice that the sizes of global function objects are noted in the
symbol table of some shared libraries are 0. I do not know the command
line switches with which these libraries were built. Is there a way to 
"force" the linker to record the size of the function in .symtab? 
Alternately, is there a way to figure out the size of the function
from the .symtab ?

I have GNU ld version 2.9.5 (with BFD 2.9.5.0.22).

Thanks for your help,

Bharadwaj
