Well, you *really* should regret that you didn't look into the DJGPP FAQ 
list (available as faq102.zip from the same place you get DJGPP), because 
it explains how to overcome this:

2.8   Q: How do I configure my system to get optimal performance under
         DJGPP?
      A: That depends on the amount of RAM you have installed in your
         machine.  Below are some guidelines to help you.

          1) If you have 4 MBytes or less RAM installed:

             * Don't use *any* memory manager.
             * Remove any TSR and device driver you don't absolutely need
               (like SETVER.EXE, HIMEM.SYS) from your CONFIG.SYS and
               AUTOEXEC.BAT.
             * Get a disk cache which works from conventional memory and
               configure it to 256K size at most, or don't use a cache at
               all.
             * Do *not* install RAM disk; point you TMPDIR environment
               variable to a directory on your hard disk.
             * Stubedit gcc.exe and make.exe and change the "Maximum
               amount of virtual memory to keep when spawning" to zero.

             With this configuration, GCC will still run out of free
             physical RAM and page when compiling large C programs and
             most C++ programs.  Also, you most probably won't be able to
             run recursive Makefiles.  Plan to buy more RAM as soon as you
             can.

The last recommendation about stubediting should do the trick for you.  
If it does not, please post your system configuration and what go32 
prints when called with no arguments.
