Hi All.
Recently at work I helped someone figure out that when working with ld,
the name of a function "foo" gets turned into "_foo" by the compiler.
(It took this old-timer 15 minutes to solve a problem he had been working
on for two days!)
I'm pretty sure this dates back to PDP-11 days. I'm wondering
"why?".
Why did the C compiler prepend an underscore to function names?
Thanks,
Arnold
