thanks for being tolerant of newbie confusion.

i *am* looking at some other issue, though as it's in template-land, and
i've lived a temperate template-free life heretofore, i may have to
declare defeat.  stay tuned.

yeah, that's why i thought, maybe parsing the pre-processor output,
rather than the pre-processor input, wouldn't take more lines of code
(but, *would* take more CPU cycles -- maybe too many more? -- given the
code expansion after all the #include files have been, well,

cheers, Greg
