I found what I think are some bugs in GNU Make 3.79.1 under VAX/VMS 7.1. I
have already fixed them on my end, but I thought I'd let you know what I did,
in case someone else asks, or if you want to incorporate them in a future
version.
I suggest you run these changes by one of your VMS experts, rather than
just take my word for it, as I can't test for the Alpha platform.
First some small problems. In order to get Make to compile at all, I had
to make the following changes:
In FUNCTION.C Line 131: "int len" should be "unsigned int len".
In VARIABLE.C Lines 204-205: I could not find any variable "listp", so I
just commented these two lines out.
In CONFIG.H-VMS Line 16: I commented this line out because my system does not
provide its own alloca(). I also uncommented line 13,
though I'm not sure why, because nothing seems to use
the C_ALLOCA macro anyway.
OK, now for the real reason I'm writing this. I found that for some reason,
when I used an object library to store the .OBJ files, Make was not reading
the time stamps in the library correctly. I am in Central Standard Time,
and it seemed like the time stamp returned by decc$fix_time on line 82
of ARSCAN.C was offset by the difference between CST and UTC. So I changed
this line to:
val = decc$fix_time (&mhd->mhd$l_datim) + timezone;
After that, it worked correctly. I haven't tested this in daylight savings
time yet, but I guess I'll find out next Spring.
Also in ARSCAN.C, by the way, on lines 69, 153, and 164 is the if statement:
if (! status)
This is incorrect. VMS system calls use bit 0 of their return values to
flag errors. So odd-numbered return values indicate no error, and
even-numbered return values indicate something went wrong. These lines
should be:
if (! (status & 1))
I hope this is helpful. Thanks very much!
