> There is a problem with djgpp and drdos version 6.  I ran into this problem,
> which has been confirmed by Peter Stephenson (see below).  I haven't identified
> all of the parameters, but here's what I have.
> 
> In running the program pagetest (djgpp/samples/pagetest), with a command line
> parameter of greater than say 3000, the program exits, leaving only a few 
> hundred bytes of ram free.  Before running it, 617K was free.  Further attempts
> at recompilation of any program with gcc were met with errors such as untermin-
> ated if statement in the header file(s).  Examination of the header, such as 
> stdio.h, revealed no problem.  Recompilation with gcc -E, revealed spurious 
> characters inserted into the .i file many times at the endif statement.  
> Editing the .i file and continuing the compilation with gcc was successful.
> Running gpp did not yield errors!
> 
> I have tried different configuration parameters.  It appears that pagetest did
> not swap to disk when the command line argument was lower than about 3000 and
> the memory problem and compilation problem did not occur.  I reloaded a fresh 
> copy of djgpp when the problem occurred but this did not fix it.  Rebooting 
> did not fix the problem.  Changing the swap drive from ramdisk to hardisk
> did not seem to matter.  I'm not sure if disabling the disk caching program
> had any effect.  The problem seemed to clear up by itself however and I am
> reluctant to pursue defining the problem further.  
> 
> My system is a compaq '386 with 10 MB ram, a 130 MB rll drive.  Drdos is 
> configured to load everything into hi memory and drive d is a superstor com-
> pacted drive.  I also tried to compile from uncompressed files but to no avail.
> 
> I apologize for the sketchy details, but I don't want to disable 
> gcc in my system right now.
