file offset of __DATA, __bss and __common

file offset of __DATA, __bss and __common

Following is the output from 'size -m -l XUL'. For the life of me I cannot figure out the file offset of the __DATA, __bss and __DATA, __common sections.

I tried to use heuristics to divine the file offsets but I seem to end up in the __LINKEDIT segment :-(.

Do I correctly understand that __DATA, __data = __bss + __common?

	Thanks, Joel
