Hi,
I'm not sure what happened during the compiling of the gcc compiler. My
original libgcc.a did not have the correct objects in it to be moved into
ROS msvcrt.dll. I dumped the Windows version of libgcc and found _alloca.
So, I just copied it over to my linux box. It worked, and ROS boots okay
on my Windows 98 se box. Just look at previous posts, I do not know. I did
exactly what the ROS GCC cross instructions said to do.

Thanks,
James
