I too had that problem awhile back, but I found a workaround...

I made a program called 'bin2s' which converts binary files into as files
which can be assembled. djgpp has no problem assembling very large .s files...

Here is the source:

#include <stdio.h>

void main(int argc, char *argv[]) {
  FILE *in, *out;
  char *outfilename;
  char *token;
  int length;
  if (argc != 4) { 
    printf("Usage: bin2s file.dat outfile.s \"token_name\"\n");
    return;
  }
  in = fopen(argv[1],"rb");
  out = fopen(argv[2],"wb");
  if (!in || !out) {
    printf("Error: file not found\n");
    return;
  }
  outfilename = argv[2];
  token = argv[3];
  fseek(in,0,SEEK_END);
  length = ftell(in);
  fseek(in,0,SEEK_SET);
  fprintf(out,".file \"%s\"\n",outfilename);
  fprintf(out,".text\n");
  fprintf(out,".global %s\n%s:\n",token,token);
  fprintf(out,".byte ");
  while (length--) {
    static int firsttime;
    static int linecount;
    if (++linecount > 14) {
      linecount = 0;
      fprintf(out,"\n.byte ");
    }
    else if (firsttime) fprintf(out,", ");
    firsttime = 1;
    fprintf(out,"%i",fgetc(in) & 0x000000FF);
  }
  fprintf(out,"\n\n\n");
  fclose(in);
  fclose(out);
}
