// file iff __ACE_INLINE__ is defined. But, in the original, highly
// optimized Sun IIOP code, much of what is in the inline file was
// here ready to be inlined at a moments notice and ALWAYS. So, in
// this ONE file, we defer to David Brownell's considerable prowess at
// creating typecode interpreters as well as to the ACE convention of
// placing inline functions into separate files.
