   The current implementation of set_section_start() can't handle 64-bit addresses
   if you've compiled the 64-bit linker in a 32-bit environment.  The problem
   is that strtoul() uses unsigned longs.  I have attached a workaround for this.

	   * lexsup.c (set_section_start): Handle 64-bit addresses is 32-bit
	   compiling  environments.

Thanks for the patch.

I think we should probably just use bfd_scan_vma instead of strtoul.
