Getting make file errors

[Steve Scott]

Welp, my face is probably going to be many shades of red over this one
BUT I have RTFM and I can't seem to find what I need.

Specifically, I have some sources from another division in my company
for which I will soon be responsible.  The development machines
(Suns with Sun OS 4.0.1) and my machines (Apollo Domain OS 10.2,
Sys V.3) have the usual small compiler differences which I can
(usually!) workaround

But, I am having trouble with a couple of make files.  The problem is
that the make program will stop with errors like:

***Error code 28

OR

***Error code 1

or something like that and I CANNOT find where these different error
codes are documented and what they mean.  At least, they are not
in the man pages on my machine.  I know I can use the -i switch
and ignore these errors but I may be masking something important and
besides that, I just wanna know what is going on here

Any help or ideas?

Thanks in advance,
