After much cursing and swearing I finally managed to get dj's gcc working on
my PS/2 model 70.
I found that I had a program called ld.exe on my path before the one required
by gcc.  I can now get the following to compile and run,  but!!!!!! when it
reaches the 4Meg allocation it bombs the machine and I get an IBM code 113
on the screen with the disk light continuously on.  After switching off and
on I find that my GCCTMP dir has a 0 byte paging file in it. Has any one got
any ideas why this program should run OK if I remove the tmalloc(4000000);
and is it anything to do with MCA versus AT bus? Thanks in advance Robin.

BTW I have nothing using XMS unless there's shadowing going on in some way
i.e. I have eliminated all diskcaches etc.

		for(i=0;i<n;i++) ptr[i] = 'b';
		printf("                     & assigned to\n");
		}
	else printf("can't allocate %10d bytes\n", n);
	free(ptr);
}
