This statement is only true in the UNIX(TM) world. It still just plain blows
me away when I encounter people who have never used a compiler that didn't
generate assembly code. My experience, measurments made on assemblers I've
written and used, is that 40 to 60 percent of assembly time is lexical 
analysis. Formatting and writing assembly code in a compiler can add 10 or
more percent to compilation times, in non optimizing compilers it can be 25%.

Generating a linkable file directly is a major performance win. Why does the
UNIX world tolerate such slow compilation?

What Duncan suggests will work. But it will be sloooow.
