If you ever add .o files to
conf_prog_SRCADD
(described earlier), and if those .o files need
to be generated from .c files, you will need to
list those corresponding .c files here:
define(`conf_sendmail_SRCADD', `myfilter.c')
Here, we add a source file to the source file list for the
sendmail program only. To add source files to
all programs, eliminate the _prog_ and use
confSRCADD instead.
It is very unlikely that you will ever have to change this value from
the one that is predefined for you in your
devtools/OS file.
