Well, what does 'Make a library from all object files' means? You must
use 'ar -r' to do it. For example: 

                        ar -r linkit.a *.o

I argee, 'Disassemble' is not clear enough. It means 'extract all modules
from library pmode.a'. In general, I'm using the same technology in all cases
when LD says 'memory exhausted' on one library (in this case, pmode.a).

Example: (about POVRAY).
(There is about 30 object files and several libraries).
(Making a library from object files)
ar -r povlib.a *.o
(removing object files)
del *.o
(Extracting objects from pmode.a)
ar -x pmode.a *.o              // Correct me if I'm wrong 
(linking)
gcc -o povray.exe (objects from pmode.a) povlib.a (other povray's libraries)

And all OK!

(In Povray's documentation there is a note that authors were unable to 
compile with optimizations and link it with DJGPP V2. It is possible to
link it with DJGPP!!! But, with some inventions...
And IMHO DJGPP'ed programs works much better in OS/2 (multitasking).
I'm running Povray in OS/2 and it works about 4 days, and it is possible to
do something else efficiently => OS/2 -Rulez!) 

If you are interested in povray ('s compiling and linking), you can download
sources from ftp://re.tsu.tomsk.su/pub/povray.

IMHO, is it WATCOM C/C++? There were some questions about MATCOM(Not WATCOM!).
