Hi,
I am getting link errors like below when I compile my
code(systemc) which is  on cygwin 1.5.23 with gcc
3.4.4
(systemc is a c++ class library) I may be wrong but I
feel the errors are related to the gcc in cygwin. I
searched the archive but couldnt find any posts
related to this. Can anyone can give me any pointers
to what might be the problem.
