  Comments are replace with one blank. I think consecutive whitespace is
stripped, too, but my standard isn't handy.

#define foo(a,b) a/**/b

doesn't work for concat in an ANSI compiler for just this reason, but
your suggestion that it works on pcc is correct (in most cases). A
conditional definition of the macro will probably help.
