I don't think it's that bad, Richard. As davem points out, the dead
code elimination works OK. Chris has a counter-example but I was not
able to reproduce that with 22.214.171.124.
The only problem I'm aware of is this tendency to leave dangling strings
in .rodata. Unfortunately you can't work around this with the linker
and -fdata-sections either. See
But still, doing the conditional compilation at compile-time rather than
preprocessing-time is so *nice* that if you don't have too many literal
strings floating about it may be justifiable.
In cs89x0.c you reduce the object size by 1.5k by setting DEBUGGING to
literal zero - no #ifdefs in sight.
