g++(1) shows a switch to turn this off:

       -fno-default-inline
           Do not assume inline for functions defined inside a class scope.
             Note that these functions will have linkage like inline func-
           tions; they just won't be inlined by default.

which implies that it is on by default.

Excessive use of inline can really suck if there is ever a need to
trace through the code in the debugger.  I'd much rather have easy
debugging than a few percent speed increase.
