Re: Attention ROOT users: bug in GCC

	Hi Matthew,

sorry, but this is a real bug: 'nm' shows that GCC looses completely 
*the definition* of the function which is in fact present in the source file
and as a result you get an unresolved reference at linking stage.
It is not a matter of inlining or not inlining a function, it's a matter 
of *loosing* it's body.

					Regards, Pasha.
