While compiling a C program recently with the Minix V1.2 Compiler on
a 80386 machine the compiler aborted and gave the following message:

error: Bombed out of codegen.

By selectively commenting out pieces of the program I traced the problem
down to the following single statement:

	sum += 0xFF & *p++ ;

where p is a character pointer and sum is a long. I found that I could 
work around this problem by rewriting the C statement as follows:

	sum = sum + (0xFF & *p++) ;

Question: Is there a later version of the compiler that is more stable
or an alternative C compiler that runs under Minix.
