Hi folks,

There appears to be a bad problem with VIM or the djgpp packer ``djp''.
I installed both on my computer, and merrily packed vim, make, ld...
ie all the files I use often, the idea being that it should reduce swapping.

The result was that vim systematically corrupted CPP.exe, whether or not
cpp.exe was packed. This seemed only to occur when vim was packed. It's
quite possible VIM overwrote something else when it was not packed, but
I have yet to discover this... (hopefully not!)

I have used VIM on the college pentiums for a while, without ill effect,
but of course they are set up differently.

My advice is to avoid djp and vim for a while, until the problem can be
isolated.

My setup is:

TI 486 SLC 4Mb Ram 25Mhz
Smartdrive
Dblspace: THE OLD VERSION, ie BEFORE DOUBLEGUARD, so it can get its internal
          buffers overwritten! In fact, I am wondering whether this could not
          be the problem: does the decompress code in the stub reserve enough
          dpmi memory to be sure that it does not write over other stuff/is the
          dpmi server set up right at that stage, etc...

go32/v2 version 2.0 built Jan 23 1996 22:03:02
Usage: go32 coff-image [args]
Rename this to go32.exe only if you need a go32 that can run v2 binaries as
 well as v1 binaries (old makefiles).  Put ahead of the old go32 in your PATH.
