I used this trick too and it does make a large difference on my system accessing
the harddisk (through SMARTDRIVE and DBLSPACE).

I have a 486SLC 4Megs Notebook (25Mhz, no FPU processor) and 80Mb Harddisk.
I use smartdrive (1Meg), DBLSPACE, have not made my CONFIG.SYS and AUTOEXEC.BAT
as small as possible (eg HIMEM is installed), so I have not followed the advice
in the FAQ, simply because I use my computer for lots of things that require
all this junk, and I don't know of an easy way of choosing configurations on
bootup.

It might also be relevant that I used to use gcc realmode in v1 because the
protected mode gcc were 2 orders of magnitude slower.

QUESTION:

I also have a question: CC is an executable of more that 1Mb, how is it possible
for DOS to load it given that DOS can only access 640Kb of conventional memory.

Ta,

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.
