Subject:	Mem. mgmt. in djgpp

Hi. Sorry to hassle the newsgroup, since after a week or so of reading it
it's clear I'm out of my league here. I don't know anything about page
frames and UMBs; I just want to compile C code for DOS.

So I downloaded djgpp, and I can compile the sample program provided.
But most compiles are very, very slow on my system (386/20, DOS 5.0, 
8MB RAM); often they crash my machine entirely.  A couple of readers 
(thanks to John Mandeville, Eli Zaretskii, and Stephen Turnbull) suggested 
I post my system configuration and ask, nicely, if someone has advice.

So: I have 8 MB RAM. I run Windows 3.1. My config.sys always has these lines:

files = 30
buffers = 30
shell=c:\dos\command.com c:\dos\ /e:1000 /p
stacks=9,256

plus zero or more of these memory-management things:

dos=high
device=c:\windows\ramdrive.sys 1024 /e
device=c:\dos\smartdrive.sys 1024
device=c:\windows\emm386.exe noems x=a000-efff

Inside autoexec.bat, I set DJGPP to c:\djgpp\djgpp.env, I set GO32TEMP 
to d:\tmp, and I set TMPDIR to d:\tmp, too, if there's no RAMDrive and
to f:\tmp if I've set up a RAMDrive. My C: drive has little space
left -- maybe 2 MB -- and my D: has maybe 9 MB.

I've seen a lot of discussion of these -- emm386, especially --
in the news group. The FAQ seems to recommend a RAMdrive; I've always
figured caching is good; and yet I just can't get things going at any
reasonable speed. Keeping in mind that I'm running DOS 5.0, can
someone suggest an intelligent combination of these memory options
that will help me compile in real time?

Sorry, again, for the low-level hassle,
