Perl script that looks for Posix functions that haven't been
protected by adding `HD' to the beginning of the name. It
takes a list of .c file names as arguments.
./bin/errors NEW
A filter that takes a function prologue and function body as
standard input and updates the error list in the prologue
based on the function body. You must add the `ERRORS' or
`Errors:' field to the prologue before you pass it through
this filter or else the errors come out as a separate
comment. The errors field must be terminated with a blank
line in the prologue so we know where the end is.
I may enhance this in the future to take an entire file as
standard input instead of individual functions.
