I'm running this at the grace of my and my husband's workplace, and
we're trying to limit the bandwidth usage. If people get into the habit

No attachments. 

If you want to share code snippets, post inline. If you want to share
larger pieces of code, put them on a webpage and use your bandwidth.
This bandwidth is for discussion only.

I can't see a need to have separate header files for each set of
#included code, nor to surround the #included code in #ifdefs. C will
only link the headers once, it should be fine to multiply include them
if you do wind up doing so.

Easy-peasy. 

At various points in the program, put the following: 

#ifdef DEBUG
 printf(logfile, "The program is at this stage, with these variables
having values foo, bar and baz");
#endif

(only correct the syntax. And don't forget to open and close the logfile
at the start and end of the program.)

Does lint still exist? Anyone know?

Do you use any pointers?
