Re: [Bashdb-devel] introduction (James Michael DuPont)

[James M. D. <mdu...@ya...>]

Thank you very much for the detailed explaination.
Yes, I should have included the file with me,
or even a -x copy of it.

On that note, do you have a way to -save-temps like gcc does, like +x
so that you can capture the fully post-preprocessed files?

I am cvs updating and will tell you how I fare.

it is funny, but i had a feeling that those long indentifiers were
created out of some hashing scheme, I encountered similar longs ids
using hashes in shell before, just concatinating the symbols into
one...

Happy new year!
